interested to see this topic as I was wondering the same.
Last week I responded very quickly to an advert, both on here & also to the email in the userID. I was the only person who responded on here.
I never heard anything back until I saw the sale item was now reported as sold…
Seller indicated in original advert he wanted paypal but I had no idea if his reported email adress was linked to his paypal account.
Now I have no idea what went on in the background in this instance but it sounds like some of the posters are suggesting a paypal race is the only answer!
If that's the case so be it but then perhaps it is polite to describe it as such. It seems a shame that there are so many 'buyers' who are screwing things up by not following through with their promises.
