Pretty much. I've had £270 in just over a year. You sometimes have to wait a while for it to become payable, but it's always come in the end. You have to click through to websites (e.g. M&S) from the Topcashback link, but otherwise no different.
Gabriella - doesn't work for grocery shopping sadly, but pretty much everywhere else! I was sceptical when one of my friends told me about it first of all but it genuinely works. I'm not one for scams!
