Your options will depend partly upon
(a) the amount involved ; and
(b) the willingness of the person paying you the money to transfer it via your chosen method.
For example, if it's a relatively small amount (and the person paying you the money is amenable to the idea) then using PayPal is probably the best way to get the money to you with minimal charges. (The only cheaper way would be for you to collect the money in cash, or have a friend bring it back for you, and exchange it at whichever exchange facility, such as Travelex or the Post Office, is offering the best rates).
However such methods aren't appropriate if, for example, you're transferring the proceeds of a house sale.
So some further information from you might help here.
