Some Reasons why Retail Arbitrage is Dead

Retail Arbitrage is buying goods from retail stores then selling them on online like ebay or amazon
First it make the buyers mad once they look on retail stores having a lower price. Then they send their products back to ebay or amazon. This make amazon or ebay look bad and people are less likely to buy from them.
Second If you sell on amazon, the categories are always changing. so one day you could be making 5k a mouth then boom like out of no where your category is restricted. Now you dont have money to live up to your life style. This is what happen to people after Retail Arbitrage got Ban.
Third Costumer warranty. What happens if the costumer product brakes. and wants to another of the same product. You are the one who is going to pay out of pocket.
If you get caught in ebay you will be ban from posting products and also getting your PayPal ban too. If this happens on amazon you will be ban and will not be allow to sell your products on amazon.
