Quick scan: the deals with the clearest value
The strongest current prices are an account-dependent MuscleTech protein stack at $26.37, Costco Premier Protein shakes at $23.99 for 18, and a Mikolo home gym at $739.99. Vitacost has a short brand-sale deadline on Monday morning. iHerb is showing a first-order discount, but no end date. None of the offers below has enough evidence to call an all-time low.
Prices and availability were checked on Sunday, August 9, 2026. Amazon offers come from Slickdeals deal pages and may be account-specific. Costco's page uses warehouse pricing, which can differ online and by location. A missing cutoff means the source did not publish one, not that the price is guaranteed to last.

Amazon: the lowest prices require the right account and the right clicks
MuscleTech whey is the week's best protein-powder price
The MuscleTech offer has the cleanest math: the deal page shows $26.37 against a $75 regular price. The final figure requires two coupons—$15.07 off the one-time purchase and 40% off through Subscribe & Save—so choosing only one of them will not reproduce the headline price. The page says the deal is $48.98 below its next-best available price of $75.35. 1
That is a strong current comparison, not proof of an all-time low. Slickdeals calls it the lowest known offer found when posted, while comments show the usual Amazon problem: some accounts saw one or both coupons, and others did not. Check the final cart after signing in. If the 40% coupon is missing, the deal is not $26.37 for that account. 1
Fish oil is a real multibuy, but the savings depend on buying two
Nature Made Burp-Less Fish Oil reaches $24.76 for two 320-count bottles, or $12.41 each, after the $13.07 clip coupon, the 35% multibuy discount, and 5% Subscribe & Save. The source also says the price is lower than the previous front-page deal, but it gives no exact historical low. The deal page shows +52, 15 comments, and 34.7K views, and does not state an expiry. 2
Treat $12.41 as a per-bottle price only if you actually want two bottles. The page says the coupons are select-account and typically one use per account; an extra Subscribe & Save tier may apply when five or more items are in the same order, but that is not needed for the quoted price. 2
K2 and probiotics are cheaper, but their evidence is thinner
Sports Research Vitamin K2 is $9.69 for the 60-count, 100-mcg version after a 30% coupon and 10% Subscribe & Save. Slickdeals compares it with a next-best price from $13.73, not with a verified historical series. One commenter could not see the coupon, so the same account check applies. 3
Vitamin Bounty Pro-50 is $12.99 after a clipped 45% coupon and 10% Subscribe & Save, versus the post's $30 comparison price. It has a +4 score, one comment, and 668 views—enough to make it a live lead, not enough to make it a community consensus pick. The source does not provide price history or a current stock confirmation. 4
One tempting Amazon multivitamin is not in the active table. The One-A-Day Men's Complete 200-count offer reached $6.32 after two coupons and Subscribe & Save, but the deal page now marks it expired. It also shows that Amazon deals can disappear before the next weekly check, even when the post has a strong +45 score. 10
Costco: useful protein prices, but no published price history
Costco's warehouse-savings window runs July 27 through August 23, 2026. The page gives warehouse prices and limits, but warns that prices can differ in Alaska, Hawaii, Puerto Rico, Business Centers, and online. That makes the physical warehouse price the anchor for the two ready-to-drink deals above; Costco.com may not reproduce it exactly. 5
At the listed warehouse prices, Premier Protein works out to about $1.33 per shake ($23.99 / 18), while Muscle Milk is about $1.39 per shake ($24.99 / 18). Oats Overnight is also listed at $24.99 after $8 off for 14 shakes, or about $1.79 per shake. Those are simple current-cart comparisons; Costco does not publish a regular-price series on the page, so none is a historical-low call. 5
The same window includes $8 off Orgain Organic Protein, $5 off Orgain micronized creatine, and $6 off Orgain collagen peptides, plus savings on Force Factor Total Beets, Kirkland vitamin C, calcium citrate, glucosamine, Nature Made iron, and two vitamin D3 products. Because the source does not expose the regular prices for those entries, compare the live shelf or cart price before deciding how deep the markdown really is. Purchase limits also vary: six for the Orgain protein, creatine, and collagen items, and 15 for many vitamins. 5
Vitacost and iHerb: act on eligibility before the deadline
Vitacost's current promotion page lists automatic discounts rather than promo codes. The most useful health-oriented cluster is 20% off New Chapter, Aloha, Ancient Nutrition, Greens First, and several other listed brands. It also lists 15% off Dymatize, Rise Bar, and Health Plus. All of these entries show an end time of August 10 at 7:00 a.m. ET, which is 6:00 a.m. in the channel's UTC-05 display time. 6
This is a good use for a cart you already planned to place, not a reason to buy an unfamiliar supplement. The page does not provide a product-level regular price, sale price, or historical series, and it shows no code to stack. Verify that the brand and item are eligible before checkout; the percentage alone does not establish a historical low. 6
The official iHerb promotions page currently displays 20% off a first order. It does not expose a deadline, minimum, product list, or broader sitewide scope in the accessible page. That makes it usable only for a genuinely eligible first order, and it is not comparable with the older recurring codes that appeared in earlier weeks. Confirm the country selector and the discount in the final cart before treating it as a live saving. 7
Fitness equipment: one near the page's floor and one cheap accessory
Mikolo's M11 Smith machine is $739.99 at Walmart, down from $1,400. The Slickdeals page shows earlier prices of $746 on February 14 and $800 on June 25, so the current price is $6.01 below the lowest earlier point displayed there. That is the strongest historical signal in this edition, but it is still only the history exposed on the deal page—not proof of an all-time low. 8
The 20-lb Signature Fitness dumbbell pair at Woot is $37.99. There is no regular price in the source, but the page shows an earlier front-page price of $37 and a popular-deal price of $38, putting the current offer near its observed community floor. Prime members get free shipping after signing in and selecting a shipping address; everyone else pays $6 per order. One commenter also flagged oiliness and a strong smell, a reminder that the lowest sticker price is not the whole purchase decision. 9
What the historical context supports
- Near the lowest displayed price: Mikolo M11 at $739.99, below the $746 and $800 earlier points shown on the page. This is the best historical signal here, but not an all-time record. 8
- Near a prior community floor: Signature Fitness dumbbells at $37.99 versus a displayed $37 front-page deal and $38 popular deal. No regular-price anchor is supplied. 9
- Strong current comparison, not a verified low: MuscleTech at $26.37 versus $75 regular and $75.35 next-best pricing; the page calls it the lowest known offer when posted, not an all-time low. 1
- Lower than an earlier front-page deal, exact floor unknown: Nature Made fish oil at $12.41 each when buying two. 2
- No price history supplied: Costco's item-level savings, Vitacost's brand promotions, and iHerb's first-order offer. Their stated discounts are current promotions, not historical-low evidence. 567
No deal in this edition clears the evidence bar for an all-time low. The practical winners are narrower: MuscleTech if both Amazon coupons appear, Costco protein if your warehouse price matches the listing, and Mikolo if you want a large home-gym purchase near the lowest price shown on its deal page.
How to check the final price
- Amazon: Sign in first. Clip every coupon named in the deal instructions, choose Subscribe & Save where required, and inspect the final cart total before placing the order. A coupon that is absent from the account removes that part of the deal. 12
- Costco: Treat $23.99 and $24.99 as warehouse anchors, then compare Costco.com or your local warehouse. Keep the item limit in view if you are stocking up. 5
- Vitacost: Use the automatic brand discount, not a code that the current page does not show. Confirm the product is in the listed brand group and check out before the Monday morning cutoff. 6
- iHerb: Treat the 20% offer as first-order-only until the cart confirms otherwise. The page does not publish a deadline or wider eligibility. 7
Expiry watch
- August 10 at 6:00 a.m. channel time / 7:00 a.m. ET: Vitacost's listed brand promotions, including the 20% and 15% health-product offers. 6
- August 23: Costco's current warehouse-savings window, including Premier Protein, Muscle Milk, Oats Overnight, Orgain, and the listed vitamins. 5
- No stated cutoff: MuscleTech, Nature Made fish oil, Sports Research K2, Vitamin Bounty Pro-50, Mikolo, and the Woot dumbbells. Their pages show live or not-expired status at posting, but prices and coupons can change without notice. 14
- Already expired: One-A-Day Men's Complete at $6.32. It is included only as a reminder to recheck status before acting on a cached deal. 10
The order of action is straightforward: check Vitacost before Monday morning, compare your Costco location against the warehouse anchors, and sign in to Amazon before deciding whether any coupon stack is real for your account.
