i just found this app which works similarly like shopitize
there are many other items available for cashback.
it says maximum refund for this product will be £1.55
but i think it depends on which product you buy from all eligible range and if you buy anything for example for£0.69 then you will get a refund of £0.69 not £1.55
hope it will be useful for someone
this is my first post for this kind of app so please ignore any mistake :)
