I have a friend who owns a power equip shop.
A customer came in and special ordered a mower putting it on his cc.

Once my friend ordered the mower there was no returning it to the wholesaler.

The customer came got the mower used it a couple of times, got "buyers remorse" And wanted his money back.

There was nothing my friend could do as the cust special,ordered it and used it so,he refused to,take it back.

The customer went to the credit card co and said the mower was not the one he ordered.
My friend showed the cc company the signed order slip from the customer and the slip from the wholesaler. All matching, same make, same model number
The cc co did not care and took the $6500. Right out of his bank acct.

So my friend was stuck with a used mower he finally ended up selling for less than his cost.

So in my mind the right not to accept returns unless it different than what customer ordered or described improperly by the seller is a fair policy. Why should someone else suffer because a customer had buyers remorse or worse returned the item broken.

Also i am a landscaper and I had a customer want brown cedar mulch so i got and installed it only to have the customer decide later they meant pine bark and refuse to pay. The customer is important as we would not be here without them but there are many people who want something for nothing and know how to get it...sadly at the expense of honest people.
