This question has probably been asked a million times, but I've tried using a 20% discount code that I found on MSE for an Ebay purchase. Several people who never received the code via e-mail say that it worked for them.
Just tried it and it accepts it initially and then it changes to "This redemption code is linked to another PayPal account and can't be used with this PayPal account". I've had my Ebay account since 2001 and have never received one single Paypal code. Do you have to spend a certain amount to receive codes? My Ebay and Paypal e-mail are the same.
Lastly how does the Quidco/Ebay thing work? I want to purchase an item for £75. How much will actually track?
