It makes no sense when you try to buy an item on the flea market and there are less than the number you attempted to buy left that it tells you that instead of just selling them to you.
 
If I want to buy 100 of something, I clearly also would like to purchase 99 of it.
 
Instead you constantly get spammed with notifications saying "Oh sorry, we know you wanted this item but there's fewer of them left now so fuck off youd on't get any" just sell us the damn items that are left.
