Has anyone else been 'caught' by the small print in their advert about adding VAT at 17.5% and then after paying by PayPal getting a separate PayPal request for the VAT?

Happened to me today until I pointed out that HMRC have strict rules about showing VAT on the invoice at point of sale... at which point they agreed to 'waive' the VAT charge blaming eBay rules (also not true).

Hmmmm....
