Excuse my ignorance, its been a while since I've purchased through paypal. I have researched the fees (which used to be 4%) and it appears that if the transaction is within the UK and made from a debit card there are no fees :-/55 + fees + post
Thank you @BertzThere are fees even though if you are sending money it says no fees , but the seller will be charged so say you send £55 at a guess seller would receive £51. So its always best to add your own fees ontop or do it as owed.
Search google for a PayPal convertor to figure out fees
Note if you send money as a friend instead of goods then neither gets charged fees but as a buyer your not protected
