Instructions:Hi, not sure if it's a deal or should go under vouchers, so please feel free to move it. I just got 40% off full price items for 2017 of calendar club. This is how:
Go through TCB to get 10.6% cashback although this may get rejected as using a code not advertised. Use code 1E17 for 20% off when you spend over £10, submit code.
Then submit a different code 1A17 as advertised on TCB.
Worked for me, hope this helps some.
Offer valid until end of the week
