I’m sure someone was complying maliciously here, but I’m not sure who.

Everything in the store was on ‘sale’. What they do is mark up the price, then discount it back to the normal price. For every single item in the store. So there are hundreds of these little printed standee signs everywhere next to each little thing.

Looks like management forgot to define a markup+discount to an item, and a programmer and/or sales staff just abided by the ridiculous ‘everything must be on (fake) sale’ directive.
