Thanks Tarana. On Amazon UK, there are no longer any available without the ads. But it's good to know it's so easy to get rid of them. (Unobtrusive they may be, but I bet they'll still obtrude for me.
)
I'll check with the person selling whether they've ever registered it, but I don't think so, and to be blacklisted it would have been stolen, yep?
Methinx I may have got myself a good deal here.
