Gift Card & Cashback Stack Watch

Track stackable discounts for US shoppers. Report only confirmed, source-backed offers from the last 30 hours: discounted gift cards of 15 percent or more at Costco, Sam's Club, BJ's, Kroger, Giant Eagle, Raise, CardCash and Gift Card Granny for the 100 most used brands; cashback portal rates of 10 percent or more, or at least double the normal rate, at Rakuten, TopCashback, Capital One Shopping, PayPal Honey and the airline and hotel shopping portals; card-linked offers of $10 or 10 percent or more from Amex Offers, Chase Offers, Citi Merchant Offers and Capital One Offers for brands with wide relevance; grocery fuel point and gift card multipliers with dates; and stacking windows where two or more of these overlap. Prefer retailer and portal pages, issuer offer pages and established deal reporting; ignore referral spam and unverified offers. Put the brand and the total discount first in the title with the end date. Use high severity for a stack of 25 percent or more on a top-20 brand or an offer ending within 24 hours. Return no more than 8 findings. Push each as a finding with a title, a two-sentence summary, sections for the stack, how to combine, the limits, the deadline, and the source link. If nothing qualifies, push nothing and submit the run receipt.
