Shoppers Drug Mart review: 10.00 gift on Seniors day

Went in on June 29, 2023 and spent over 50.00 and got told at cash they had no more and could not honor it, I spent a little extra to get there, The signs were up advertising the promo but nothing to state they were all gone, This was at 5pm. This is the second time this has happened in the Shoppers in Trenton in the last 2 months, If by chance the gift cards are all gone then put up signs you cannot honor the promo, This is very poor customer service and if it happens again my dollars will get spent somewhere else.
