Well since the return process took the best part of 15 minutes for this state-of-the-art store, and I would have had no recourse if the refund didn't go through (since I had no proof I'd returned it), I won't be rushing back in a hurry. So in that respect it was a failure.

15 minutes to return something honestly seems… fine? Like I’ve gone to brick and mortar stores to return things and had it take upwards of an hour for the overworked customer service folks to make it through the line of folks

If I'd known it was going to take like 10 times longer than usual I'd have gone somewhere else or not gone on my lunch break.

if they didn't, they'd undoubtedly have mentioned it

I have no love for amazon, but besides the lack of receipt, this seems like an issue they created for themselves
