I can't see if this has been posted anywhere but, I last purchased credits at the begining of October.
I purchased 80 credits at a TOTAL of £20.
Today, I attemped to purchase more
30 credits is £7.50
40 credits is £10
80 credits is £20 PLUS £4 VAT
160 credits is £40 PLUS £8 VAT
Am I going mad?
If I attempt to purchase 2 lots of 40 credits the total = £20 and there is NO VAT on checkout ?
