I want to buy something on behalf of a family member and it needs to be in their name and I don't want to create a Quidco account just for one transaction. So could I use my Qiudco account and then when it comes to the purchase use their details? Surely the retailer doesn't pass on personal info about the buyer to Quidco so they wouldn't know anyway! The same applies for TopCashBack.
I will ask them directly but they may not reply in time as the purchase will be made today.
