There are signs everywhere explaining the sale. Please do not be like the 15 people before you asking what the prices are. Especially if the sale happens to be in a video store, if you are able to read movie titles and the synopsis, then you are capable of reading a damn sign!
Final sale... Means just that! No you cannot exchange it or get a refund. We told you that before you bought it. No, asking 3 different people on 3 different days will not get you a different answer. "well can't you just..." NO NO NO and NO! What part of that is unclear?
Please please please do not carry on for 10 minutes about how bad it sucks that the store is closing. We know it sucks. Where will you shop now? Hmmmm where will we work now?
If we tell you we don't have it, we don't have it. Asking 3 of us to check will not make it magically appear.
