never used cashback sites before, can you combing them with coupons and vouchers?

i think i must be missing out

ordered 95% of my mas shopping via the internet

with most things ive used coupons and codes

but should i really be claiming cash back too
if so which one

sometimes u can use the codes with it and sometimes it might cause the cashback 2 be rejected, but its still worth a go cos if you go thru the cashback site but its not tracked due to an incompatible code then you've not lost anything
i think they do say on some of them that its not going to track if u use unauthorised code, like i've seen that for vertbaudet so wouldnt bother going through quidco on that as the codes will give a better deal
others like m&s, price minister, you can get cashback and use codes @ the same time and works out into a very good deal

thanks i think i will go for quidco

I use topcashback.

The only place that stops me using the codes as well is Next.

I use Cashback Rewards - recently tried to include a discount voucher code on an M&MDirect (I think it was them) order & didn't get it.
