Item arrived 24 hours early, brilliant service.
Only 1 complaint. I paid £39.99 membership fee and I got it cheaper by not being a member. Not what I would have expected
Whats the point in paying £40 for better prices when I can buy it cheaper not being a member?. Also used the EXTRA10 discount code for an extra saving.
