Really disappointed with them. If you have a voucher - use it. We ran out of time and then tried to extend it by swapping it. The value we got was much worse than the original voucher but we accepted it as our fault. We received a voucher for the ‘change’ but when we tried to use it we found we could not use it with the almost standard 23% off. Annoying as to us the voucher should have been treated as cash. Now they just ignore our emails. But we did get the 15% off offer. Needless to say we didn’t bother so their loss overall.
There’s nearly always a discount code for 23% off buy a gift if you google it.
