I have some items on a popular freeads website on behalf of my girlfriends parents who are moving from their 5 bed house to a static caravan 
Ive had an email this morning regarding most of the items for sale asking if she could purchase everything. Itll be around £600 and she wants to pay me via paypal as she is bedridden after heart surgery but will send a courier today for everything after she has paid us.
What im wondering is if she buys everything and pays via paypal and then a few days down the line tries to claim the money back, is it possible for her to do that?
The gfs parents are retired so dont want to mess around with this hense why im doing it, but i want to make the right decision for them..
Regards,
James.
