Halfords have a very wide range of products and you can find pretty much anything you are looking for. They do have offers on all the time but their prices are probably higher than those offered by smaller places anyway. Their website is easy to use I found, although a couple of times I used the 'reserve and collect' feature I turned up in store to find they didn't actually have it in stock which was mildly annoying. They shouldn't offer this service unless they will guarantee they will have the product. good for their range and keep an eye out for offers, Halfords are quite convenient for finding what you are looking for.
