Top Portal Bonuses This Week

Capital One Shopping & Capital One Offers: up to 60.5% back / 47X at Klook (10/12 only)

• Portal/Extension: Capital One Shopping (public portal) and Capital One Offers (cardholders)
• Source: Frequent Miler
• Link: Frequent Miler
• Rate/Value: Up to 60.5% back / 47X (rates vary by account; UpgradedPoints separately reports up to 40% back)
• Ends: October 12, 2026 (today only)
• What: Klook is the deal of the day at both Capital One Shopping and Capital One Offers, with reported rates as high as 60% back on the tours/activities/hotel booking platform.

Cashback Portals

TopCashback: 12% Hotels.com, 15% Viator, 16% Klook, plus IHG and Expedia elevated

• Portal/Extension: TopCashback
• Source: Frequent Miler
• Link: Frequent Miler
• Rate/Value: Hotels.com 12%, Viator 15%, Klook 16%; IHG Hotels & Resorts, Expedia and more also elevated (see source for the full list)
• What: TopCashback is running increased cashback rates across many travel sites, and this does not appear to be a coordinated sale event.
• Why it matters: Because no expiry is listed, there is no deadline pressure — but if you are about to book travel, routing through the portal first adds cashback on top of whatever card you pay with.

Stacking & Gift Card Plays

Staples: fee-free $200 Mastercard gift cards (10/11–10/17)

• Portal/Extension: Staples (in-store gift card promotion)
• Source: Frequent Miler
• Link: Frequent Miler
• Rate/Value: $200 Mastercard gift cards with no purchase fee (that's the activation fee waived); limit nine per customer per day
• Ends: Saturday, October 17, 2026
• What: Staples is again selling $200 Mastercard gift cards with the purchase fee waived, Sunday 10/11 through Saturday 10/17.
• Why it matters: Waived fees turn these into a no-cost way to move spend onto a card that earns category or welcome-offer rewards — though some buyers report being able to purchase more than the stated nine-per-day limit at their local store.

Kroger / Harris Teeter: 4x fuel points on select gift cards (10/7–10/20)

• Portal/Extension: Kroger / Harris Teeter (digital coupon)
• Source: Doctor of Credit
• Link: Doctor of Credit
• Rate/Value: 4x fuel points on third-party gift cards plus Visa and Mastercard fixed-value gift cards
• Ends: October 20, 2026
• What: Save the digital coupon and buy eligible third-party or fixed-value Visa/Mastercard gift cards to earn 4x fuel points.
• Why it matters: Fixed-value Visa/Mastercard gift cards are included, so this stacks a fuel discount on top of whatever rewards your credit card earns on the grocery purchase.
