You are not alone. I'm still hoping I get my credit too. It's never happened to me before. But it's been a few days now, so I am doubtful I'll get it. And like u, it makes me hesitant to do it in the future.
Prime opinion. Can cash out to Paypal after $5. Grocery apps are good IMO (ibotta, fetch).
I still use SB for receipts and some GC purchases. But it is definitely not the same as days past.
Are you finding Costco shop cards ar a discount? I could definitely use a discount at Costco (for groceries and such not DGC). I don't have a CC with warehouse offers.
