Quidco works in much the same way as Rpoints, however it appears the people who run the site either have better agreements setup with the merchants or they are less greedy.  For example on Rpoints youíll earn 1% when buying something from www.play.com , however with Quidco the reward is 2%.  It doesnít take a genius to see where your better off directing your purchasing traffic.  Quidco offer withdrawal of earnings to a paypal account much the same as Rpoints, however it is worth noting that £5 is deducted from your first withdrawal in order to cover administration costs.  If your earning double the commission then itís obviously worth doing in the short term.  Thoroughly recommended!!
