I think the suggestion is to buy VISA/MasterCard gift cards at a supermarket, use PYB to offset the charges. The Supermarket category is only valid until 9.30.2025, but could be renewed. There is the hassle of buying ~$12,500 worth of gift cards in 45 days, and then there are the headaches which may arise try to use those gift cards.
Does Sapphire Preferred have the same PYB categories/ratios?
they also come with activation fee 7.95 per $200 or $500. im also not sure if chase will shut you down for spending $12.5k in grocery stores in a short period of time
