What this Amazon deal is worth

The average discount across the 1045 deals carrying a percentage on Ring In The Deals right now is 48%, so at 48% off this one is deeper than the typical drop in the feed — it beats 50% of everything else live today.

How we check: our tracker reads the retailer's own listing, records the price and the original price exactly as Amazon published them, and posts the deal without anyone retyping a figure. No discount percentage is shown unless both numbers came off that listing. More on how a deal gets on this page.
What we make of it
This 40 oz vacuum insulated water bottle keeps drinks cold or hot for hours, making it ideal for outdoor activities or long commutes. Its durable stainless steel construction is great for everyday use, while the double wall design prevents condensation on the exterior. However, users might find it bulky for smaller bags or cup holders, and it lacks a built-in straw, which can be inconvenient for on-the-go hydration.
Why this is a good deal
It is deeper than the typical Kitchen discount
The median discount across the 121 Kitchen deals we have live is 45%. This one is 48%.
What you actually keep
$14. A percentage is a ratio and a saving is money — on a cheap item a huge percentage can be worth less than a modest cut on something expensive, so this is the number we would judge it on.
Reasons to think twice
we have only seen this product once, so we cannot tell you whether the original price is a genuine going rate or a list price that nobody pays; at this price the shipping threshold will usually matter more than the discount; the discount is only a saving if you were going to buy the thing anyway.
