Last time I got a $50 gift card for my friend. She went to Costco with it and her purchase came to over $100. The cashier refused to let her pay the other $50 in cash. Ended up she couldn't buy all the things she wanted.
cuz I have only been to the one in richmond
and once I was with a frd and he had a membership card
he paid for his stuff then I also paid for my stuff, separately
the cashier didn't say much
