There aren’t many discount code sites that are both worth visiting and apply to British stores and customers. But there is one decent site, DiscountDiscount.co.uk, that has been around since 2004 and it fits the billing.
Amongst the top high street stores where you can get discounts for are Homebase, Argos, Dorothy Perkins as well as purely online businesses such as Hotels.com and Lovefilm.com. If you are buying tech it is always worth checking the Comet discount codes because they are always big purchases and you should be able to save a fair chunk.
You may not always save something but if there is one site you should bookmark for when making purchases it should at least be one that turns up good offers.
