Mmm, well actually they're offering "1.5-3%" on almost all product categories (less than imutual) but have added a very specific category of "Television Accessories & Cables and Tools" at 10%. So the headline is "10% cashback" but virtually every purchase would, in reality, be around the 1.5-3% mark
However, a promise is a promise so I have now added "Television Accessories & Cables and Tools" at 11%
Thanks for the headsup Kev
