Just as I'm watching the olympics, we haven't won a medal in the last 10minutes so i became bored and noticed this deal, vouchercloud are doing a 20% off offer when you spend over £15 on food.. Combine that with Halifax cash back offer of 15% off you can grab a decent deal!
WAIT I'm not finished yet, quidco also do a 10% cash back offer when you register a card.. Although not 100% if these codes can be stacked but you can defo get 2 out of the 3 offers! So for example if it all works, spend £20 it could actually cost you £13.60 if the quidco works it'll be £12.24!
Bit late for me doing my maths so I'm going to leave it there, hope people can get some use out of this! :))
