She had already sent an invoice with the agreed shipping cost and then all of the sudden she relisted with increased shipping cost, telling that it is more risky ro ship internationally. And that another buyer was about to purchase.
You do know that by invoicing you for extra shipping costs outside of eBay, that that is breaking eBay rules as the FVF also includes the postage. Its all very well berating her for breaking ebay policies but you cant then query why she didn't break them when it suits.
I think she realised that it costs lot more to send it to you in Greece with with seller protection
She realised that invoicing you the extra outside of ebay was infact breaking those rules.
She then panicked and then had to relist as ebay wouldn't have let her change the original listing.
She did it straight away..and yes it is possible that another buyer saw it straight away as ebay sends listings via email for similar things that people have missed out on previously. You weren't aware that she had relisted just for you to be able to buy and you were out of contact.
Perhaps she didn' tick the pay immediately button as on previous occasions it hasn' been an issue and her previous buyers have paid immediately so she didn't realise the button existed.
For all those virtuous people who think the seller should have just have "sucked it up" and paid the extra... You have no idea what her financial situation is ... She could need every penny to make ends meet or to provide a nice Christmas for her family and those obviously come first before an anonymous buyer.. but I don't know and neither does anyone else.
You dinged her feedback, sent angry emails, reported her and are going do your best to ensure she doesn't get her FVF refunded .. I think thats rather mean ...
