Kudos Flash Boost July 2026: 50% Off Boost Mobile, 8% on Hotels & Flights
July 1, 2025

Most months, Flash Boost rates move a few points. A merchant doubles, maybe triples if we're lucky.
This month, one merchant went 5x.
Boost Mobile: 10% → 50% back
We don't say "highest rate we've ever run" often, because it's usually not true. This time it is. If you've been on the fence about switching to a prepaid plan, or you already have Boost Mobile and haven't linked your card, July is the month that decides for you.
That's the headline. Here's everything else that moved.
July's Full Rate List
- Boost Mobile: 10% → 50%
- Expedia: 3.5% → 8%
- Hotels.com: 4% → 8%
- VRBO: 2% → 8%
- StubHub: 2% → 8%
- Viator: 4% → 8%
- Woot!: 3% → 6%
- HSN: 2% → 5%
- eBay: 1% → 4%
- Etsy: 2% → 4%
- Best Buy: new to Flash Boost at 1%
Travel Got a Real Bump
Three travel merchants jumped to 8% back this month, up from rates that were barely worth mentioning last month:
- Expedia: 3.5% → 8%
- Hotels.com: 4% → 8%
- VRBO: 2% → 8%
If you're still sitting on summer travel plans, this is the rate that makes booking now instead of later worth the math.
StubHub and Viator also landed at 8%, up from 2% and 4%, respectively. Between flights, hotels, concert tickets, and tours, this is shaping up to be the month to lock in the whole trip through Kudos.
The Rest of the Board
A handful of everyday merchants got quieter, but still meaningful, boosts:
None of these are headline numbers on their own. But eBay and Etsy at 4x their usual rate is real money if you shop either regularly, and Best Buy's debut, even at a modest rate, is worth watching since electronics purchases tend to run high.
The Layer Most People Never Turn On
Here's the part that actually separates Kudos from just "a cashback rate":
Every rate above stacks on whatever your card already earns. But most cardholders are also sitting on a third, invisible layer: card-linked offers. Amex, Chase, Citi, and Bank of America all load their cards with rotating CLOs, 10% off here, $20 back there, refreshed every few days. Almost nobody activates them because they're scattered across four different issuer logins.
Kudos auto-activates them in the background. Visit your issuer portal with the extension installed, and it's handled. At checkout, Kudos tells you which card gets you the highest combined return across Boost + CLO + base rewards.
That full stack, on one purchase, is the actual product.
For People Who Want the Full System
Kudos Free covers a lot: card recommendations at checkout, Boost cashback, approval odds, and your full wallet in one place. Kudos Premium is for people who want the whole thing running on autopilot:
Rebuilt Benefits Tracker. See every credit and perk across every card, with real-time progress bars, step-by-step redemption instructions, and an annual fee vs. value comparison so you know which cards are actually worth keeping.
Auto-activate card offers. Kudos automatically activates your Amex, Chase, Citi, Bank of America, and Wells Fargo card-linked offers when you visit issuer portals, then reminds you to use them at checkout. This is the layer that stacks directly on top of every Flash Boost rate above.
AI bill negotiation. An AI agent calls your phone, internet, cable, or home security provider and negotiates the bill down, no hold music, no calls on your end. You keep 100% of the savings, no commission fees. Tikue, our CEO, saved $840 on T-Mobile in a year, over 20x what Premium costs. Supported across most major mobile, internet, TV, and home security providers, including Boost Mobile, which makes this month's 50% Flash Boost rate worth double-checking your bill negotiation status for too.
Location Cheatsheet. Open the app anywhere, at a restaurant, gas station, or grocery store, and see your best card for that exact spot. Available on iOS and Android, with a home screen widget.
Kudos AI. Ask it anything about your spending, subscriptions, cards, or offers, including which Flash Boost rates you haven't used yet this month.
Subscription tracking and automatic cancellation. Kudos identifies unwanted recurring charges and cancels them for you with one tap.
2 years of transaction history, unlocked instantly on upgrade.
Welcome bonus tracker, with smart alerts as you approach spending targets or deadlines.
Coming soon: automatic rebooking when flight or hotel prices drop, unlimited connected accounts, and bill statement integration.
Want Premium for life instead of a subscription? Kudos Premium Lifetime is a one-time $240 payment for permanent access to everything above, plus everything built after.
The Bottom Line
Boost Mobile at 50% is the number to act on this month. Travel (Expedia, Hotels.com, VRBO, StubHub, Viator) at 8% is the category to plan around. And eBay, Etsy, Woot!, HSN, and a debut appearance from Best Buy round out a genuinely strong month.
All rates expire at the end of the day on July 31st.
