It can depend on the location but most places for me pick up within a few minutes. Burger King is usually good but I did have once where it took nearly 12 hours for it to show up, at the same place it's instant every other time before and since.
I just wanted to report my DP's for science since someone had mentioned something about MasterCard not being accepted. My linked MasterCard worked today like it usually does, even though only the Visa and AmEx logos are showing on that restaurant.
We went last night to a new place listed on SBLocal for dinner and used my linked MC but I haven't received any pending notice from SB yet. It can still show up later after the charge processes but for now I'm just going to assume it didn't work. So I went to my trusty BK for lunch this afternoon to finish Swago, used my linked Visa to be sure and by the time my order was ready I had points pending and the Swago square checked off. For science only
, I stopped on the way out and got a soft serve to pay with my MC and sure enough by the time I got to the car I had points pending from that purchase too.
