I've been using Topcashback for years and it used to be very reliable, however, over the last few years, any purchase above £100 has failed to track and a manual claim has proved to be a waste of time, every time. I've purchased 3 children bikes in the last 18 months and none has tracked the purchasing but small purchases are still reliable, however, most of the times I can't be bothered for a 30p cashback.
I've followed the advise to maximise the chances for purchases to track to no avail, Wiggle, Chain Reaction Cycles, Decathlon, Liverpool Victoria, The A A, etc, etc... fail to track the purchase but say a £30 purchase from any of them has a really good chance to get you a few pennies in cashback.
