I purchased a gate latch yesterday. it came in a cheap polythene bag. I opened it on site only to find it was not suitable for the job. I popped it back into the bag and along with the receipt returned it back to screw fix to exchange it for a different one. I was told that because the bag had been opened i could not exchange it for anything else, even though the product had not been used. I find this absolutely disgusting, I've never had a problem exchanging goods at any of my other suppliers. I use screw fix at least a couple of times a week but don't think I will be using them again.
