June 2026 Flash Boost: 25% Back at Temu, 12% at T3 Micro, 8% on Expedia and Hotels.com
July 1, 2025
.webp)
June's Flash Boost lineup is built for someone who's actually going somewhere this summer.
Book the flight. Lock in the rental. Grab the camera gear you keep putting off. Catch the concert while the lineup is still good.
Not a coincidence. It's a lineup that stacks well on the purchases that run big in June. Here's what's elevated this month.
June's Biggest Rates (All Expire June 30)
Was 5%. Still 25%. One of the highest rates Kudos runs on any merchant, period. If you had a cart sitting there last month and didn't pull the trigger, here's your second chance.
Was 6%. T3 is holding its elevated rate from May, the strongest cashback they've ever offered through Kudos. If you've been watching the price on a hair dryer, a straightener, or any styling tool, this is the month.
8% back on travel: Expedia, Hotels.com, and VRBO
All three held their rates from May. If you haven't booked summer travel yet, the window is closing. Stack any of these with a good travel card and you're looking at real returns on purchases that already run into the hundreds.
Summer concerts. Summer sports. Live anything. Book through Kudos and stack it.
Woot is Amazon's off-price outlet, more than double the usual rate. Worth a browse if you buy electronics, kitchen gear, or random useful things on the internet.
Canon is new to Flash Boost this month. If you've been eyeing a camera, a lens, or any photo gear, 7% back is a strong rate on high-ticket items. Note: Canon's rate is configured but not yet live. Check the Kudos extension to confirm availability before checkout.
4x on eBay is 4x on anything. Hard to beat when you're shopping used.
The Part Most People Skip
Every rate above stacks on top of whatever your credit card already earns. That's the whole point.
But there's a third layer most cardholders skip entirely: card-linked offers (CLOs). Your Amex, Chase, Citi, and Bank of America cards are loaded with them right now. 10% off here, $20 back there. They refresh every few days. Most people never activate them because they're buried across four different issuer portals.
Kudos auto-activates them. Visit your issuer portal with the extension installed and it handles the rest. At checkout, it tells you which card to use to maximize your total return across Boost + CLO + base rewards.
The full stack on a single purchase. That's the actual product.
Want More? That's What Kudos Premium Is For.
Kudos Free gets you further than most rewards tools. Kudos Premium takes it further still. In addition to card-linked offer activation, Kudos Premium offers:
AI bill negotiation. Kudos sends an AI agent to negotiate your phone, internet, cable, and home security bills directly with your provider. No hold music, no phone trees, no calls on your end.

Subscription tracking and cancellation. Kudos detects recurring charges across all your connected accounts and cancels the ones you don't want, with one tap. No more paying for things you forgot you signed up for.
Full benefits tracking. See every perk across every card you own, with expiration alerts before anything goes to waste.
2 years of transaction history. Instant access when you upgrade.
Welcome bonus tracker. Set your target, track your progress, and get alerted before deadlines hit.
Coming soon: flight and hotel price monitoring with automatic rebooking when rates drop, location-aware card recommendations, and bill statement integration.
The Bottom Line
June's best rates: Temu at 25%, T3 Micro at 12%, Expedia, Hotels.com, VRBO, and StubHub at 8%, Woot! and Canon at 7%, eBay at 4%. Stack any of these with your card's base rewards and active CLOs and you're looking at some of the best returns available on purchases you were already planning.
All rates expire June 30th.
