The first time I was at the store, the $200 VCGCs were all empty. I managed to get a few and it was $2k per day. The 2nd time I went back, the VCGCs were all fully stocked. The manager was there and the store was empty. He showed me the sign with the highlighted "one card per day". But he told the cashier to sell me two cards.
So I do not know what the benefit the store manager gets. He could have told the cashier to sell me 10 cards, but he did not.
