Query: very hard to return item after you bought it

I ordered online. Then, I received an email saying we had to wait another a few days before it was shipped out. We could not wait that long and found it at a local store and bought one. Then I called and sent email to cancel our order. Vender was very reluctant to cancel our order. They told us we had to wait until we got it and then call them again to get return number. After we got it and called them, they said we had to pay 15% restocking fee plus return shipment fee. End up, we kept it.unsatisfied customer
