CVS receipt coupons are based upon previous purchases + like 15% randomization in related categories (or maybe just random promotions they have going). My CVS coupons are nearly always for an antacid, nicotine cessation, or allergy medicine - then I usually get a few extra coupons for something that surprises me like beauty products or facial cleanser. There’s nothing Google involved with the CVS coupons, I’d bet money on that.
