I read on the quidco site that sometimes cashback will not track if you use a code/voucher. Obviously it varies from site to site but does it also depend on which code voucher you are using?
If possible I'd like a definitive list based on people's experiences.
No conjecture or hearsay please. Only post if you know based on your transactions you have tracked through quidco.
These are the sites I am particulary interested in.
and any other shops of similar ilk.
