I bought variable vanillas from CVS and OVs from WAG yesterday and no problem draining them at the grocery store ONE HOUR later. I'm aware of delayed activation for a while now and IME, it takes at least an hour to make sure the cards have the balance before I drain them. So far, so good. I've reach the cap on my last OBC so my next purchases will just be at WAG using Chase for Q3 5% offer. Hopefully, activation and draining will continue to be uneventful for me.
