I had an idea

for my local shopping centre Eb games and Kmart are super close

I was thinking, If I go to EBGAMES first and pick up my booster box(and get the promo)

then I go to Kmart to try and get a booster bundle and a etb

then if I do manage to get one from Kmart , can I go back to EBGAMES and cancel the preorder for the booster bundle and etb and get my deposit money back?
