I tried using the trade card in my local halfords and if it's already discounted they wouldn't let me use it. Also not trade card related, but took some broken sockets in a couple of years ago for warranty but the manager refused because I was wearing company overalls he refused the warranty as it wasn't what the tools were designed for??? So sent my wife in with the same tools and they refused to change them for her as she didn't have the original receipt. I'm sure it's isn't the case at every store, but I just gave up with halfords and gave the tools to a neighbour.
