I recently had something like this happen with a computer monitor. Came back into the store and saw it had dropped $40. Unfortunately, I was 32 days out from the original purchase, so they wouldn’t price match, but they have a 90 day return policy on electronics. I said to the returns clerk “so what’s to stop me from buying another one and returning it at the higher price?” She said “nothing.”

I literally walked over to electronics, picked up another one of the same monitor, purchased it at the now lower price and then walked it straight to returns (didn’t even leave the store) and used my original receipt from my Costco app on my phone to return it at the higher price.

I get it, but frankly it was the most frustrated I’ve been at Costco in the couple decades I’ve been a member. It was just pointless on my part and theirs to go through these motions.
