- Amazon Prime Big Deal Days run from Tuesday, October 7 to Wednesday, October 8.
- Every few hours, Amazon offers new "Today's Big Deals"—steep discounts on buzzworthy items that drop at specific times of day and are expected to sell out quickly.
- Good Housekeeping Institute-tested items from Day One (October 7) are now on sale, with the most worthwhile ones highlighted below.
If the thought of sifting through hundreds of products on October Prime Day overwhelms you, you're not alone. As a shopping editor who's covered the last seven consecutive Amazon Prime Days, I know better than anyone that navigating the e-tailer's sales can be time-consuming. Thankfully, Amazon introduced "Today's Big Deals" during last July's Prime Day—and it's essentially a cheat sheet to the biggest and most sought-after deals of the entire event.
For October Prime Day 2025, Amazon is releasing a new crop of limited-edition deals three times a day, all of which will remain available for a limited time—or until they sell out. And now that all of Day One's Today's Big Deals have dropped, our editors are pulling together our favorites. I've compiled a list of just eight flash deals worth shopping from Day One based on price data, customer reviews, and expert testing from the Good Housekeeping Institute. Plus, our editors will keep you updated as more flash deals become available throughout the event.
Stanley The Black Chroma Quencher H2.0 FlowState™ Tumbler
Why it’s hot: Stanley’s viral 40-ounce tumbler needs no introduction. This chrome-accented black colorway is constantly selling out, so we doubt it’ll be in stock for long.
Our experts say: Our Kitchen Appliances and Innovation Lab Director Nicole Papantoniou likes that the Stanley H2.0 fits easily into most cupholders, and notes that its oversized handle is comfortable to grip.
The deal: At 45% off, this particular Stanley model and color is on sale for its lowest price ever.
Why it’s hot: Naturally, Prime Day is the best time of the year to save on Amazon devices, like these Echo Buds with more than 6,000 five-star ratings.
Our experts say: These top-tested wireless earbuds impressed our Senior Reviews Writer & Analyst Olivia Lipski with their comfortable, secure fit. Plus, she found that they were easy to switch between active noise cancellation and transparency mode.
The deal: On sale for a whopping 70% off, these earbuds are at their lowest price of all time.
Bliss Bright Idea Vitamin C + Tri-Peptide Brightening Serum
Why it’s hot: More than 4,000 Amazon shoppers have given Bliss’ Bright Idea serum a five-star rating, and praise its hydrating texture and pleasant scent.
Our experts say: As our Beauty Lab experts’ best vitamin C serum pick for sensitive skin, this product stands out for its gentle formula, made with a form of vitamin C called 3-O ethyl ascorbic acid that’s thought to be less irritating.
The deal: This top-tested serum is on sale for less than $15.
Why it’s hot: I can hardly scroll through my TikTok feed without coming across Touchland’s stylish hand sanitizers. Plus, the brand’s foray into body mists has made quite a splash online.
Our experts say: Our Beauty Lab Director Sabina Wizemann loves Touchland’s unique hand sanitizer packaging, and notes that it reminds her of a perfume bottle. Plus, she finds that it doesn’t dry her hands out as much as other formulas.
The deal: This gift-worthy bundle—complete with a hand sanitizer and travel-sized body mist—is 30% off.
Hydro Flask Wide Mouth Flex Straw Water Bottle
WHY IT'S HOT: Hydro Flask is one of the most beloved water bottles among shoppers for its insulated design and range of fun colors, like this purple pick with a convenient collapsible straw.
OUR EXPERTS SAY: The GH Institute's Kitchen Appliances Lab experts have tested a range of Hydro Flask models, and the brand stands out for its leak resistant lids and temperature retention.
THE DEAL: This 32-ounce water bottle is on sale for 25% off.
WHY IT'S HOT: Get a head-start on holiday shopping with this steep deal on a top-tested gift. Year after year, the Toniebox has remained one of Amazon's best-selling toys for its interactive storytelling that's both fun and educational.
OUR EXPERTS SAY: A previous GH Toy Award winner, the Toniebox wowed our parenting editors with its easy-to-use design that keeps kids entertained independently.

Staub Ceramic 0.75-qt Petite Pumpkin Dish
WHY IT'S HOT: Whether you use it as a candy bowl or for roasting real pumpkins, this dish from Staub makes for a stylish addition to your Halloween tablescape. What's more, it claims to be oven-safe up to 572°F, making it a practical purchase.
OUR EXPERTS SAY: Staub's cookware has graced several of our Kitchen Appliances Lab's top-tested roundups, from our best Dutch oven pick for large batches to our favorite serving platters.
THE DEAL: We haven't seen this dish drop lower than $30 in years, so it's a steal at just $24.
Bose QuietComfort Ultra Bluetooth Headphones
WHY IT'S HOT: Prime Day is one of the best times of the year to save on investment-worthy tech, like these over-the-year Bose headphones with active noise cancellation and personalized spatial audio.
OUR EXPERTS SAY: As our experts' best overall noise-cancelling headphones pick, this model impressed GH Institute Data Engineer Nikolas Greenwald with its "clear and balanced" audio and top-of-the-line noise-cancelling technology.
THE DEAL: You can save more than $150 on these headphones, which is the lowest price we've seen all year.
