Not sure how universal this is, but Kroger has a “Cash Back” option under “Savings” that lists a number of beers and wines, on which you must “load” (click on) to qualify. Cash back can be either “Paypal Only” or sometimes also selectable to load onto your Kroger Shopper Card.
Sometime after you buy the item (a couple days, typically) you’ll see “Cash Back Available” when you login to Kroger.
Recently I’ve had good success loading both a $5 Cash Back and $7 Cash Back offer on Michelob ULTRA, then buying a 24-pack of 12oz cans or bottles for $20.99. Then a couple days later in my Kroger account, I see a “$12 Cash Back Available”, which I direct to my PayPal account. Which is typically available there the same day, or the next.
I’m sure there’s plenty of other combinations available, perhaps even trying for a mail-in rebate with the same purchase…dunno. But this is sure simpler than most rebates, ie filling out forms, copying receipts, etc.
Sorry if this is already covered here somewhere–too lazy to search!
