This site relies on a community of users to list top discounts, sales and money-off voucher codes. Since the onset of the credit crunch, enthusiasts willing to share tips have inundated the site, with hits up a huge 30% since last year. The site ranks the deals using a temperature gauge and users get to vote if it is hot or cold. After attracting enough hot votes, the offer is highlighted on the front page of the site. Last week, one of the hottest deals was an IBM laptop reduced from £300 to £150. Another hot deal is 90% off swimwear at bargaincrazy.com . An Oasis metallic foil print bikini set, which cost £26, is now selling for just £5. Delivery is free if you spend over £30.
