Damaged goods replaced on shelf?

Last week Thursday 23rd April, I bought some camping stuff from the Cavendish branch. I asked an assistant if they still stocked the Eco Star UV headlamp (with the UV LED). he went and fetched one from a display stand.<br> <br> When I tried it, it did not work, but he assured me that there was a plastic cover over the batteries that need to be removed. I accepted that, paid and left.<br> <br> Over the weekend I went camping, and was annoyed to find it did not work, even after replacing the batteries. A plastic cover over the batteries? - none.<br> <br> I took it back on Tuesday, and to their credit, they replaced it without any bother, but here's the thing: The replacement was in the original packaging, the original had no packaging. When I suggested to the staff that the one I had bought originally had already been returned before and simply replaced on the shelf, they actually agreed that I was probably right!!! <br> <br> No doubt hoping to sell it and hope it's not returned...<br> <br> I've got one that works now, but I was sans headlamp for the trip. Not happy.<br> <br> Vince
