Stop buying junk! How many times do you have to be bitten before you establish some kind of quality floor on your purchases? There's entire categories of products that I won't buy on Amazon because the odds of getting shit are too high. There's an old saying in Tennessee — I know it's in Texas, probably in Tennessee — that says, fool me once, shame on — shame on you. Fool me — you can't get fooled again.

> Amazon policy clearly does not state any limits on returns.

Amazon is a private company. They are not required to do business with you. That's in their policy too. Returns are guaranteed; your continued ability to do business with them is not. Though why you keep going back to them after they keep selling you items of such inferior quality I can't discern.
