Dollar stores have on average a 2% profit margin, just like grocery stores. They are not the villains here.
This is like cheating in a golf match against a professional and then saying "I got the same score as my opponent, I am not the villain here".
Do you think large dollar stores are faking or cheating their profit margin numbers?
I mean, they are cheating customers on the item price, so it goes to show they'll do illegal stuff without care, so yea, why not.
