Should Returns Be Free?

The worst returns are at Costco, I saw people returning Christmas trees with ornaments still on them just after Christmas.

You know they purchased these trees with the intent to use and return making it a flagrant abuse of the return policy. This ends up hitting us all in the pocketbook and in my opinion should be stopped. I like Costco but would prefer to see an additional 5% price drop with the return policies tightened up.
