If the item is not from an individual a retail outlet there is no tax.Question (and I may be being dense) why do a lot of buyers keep thier IDs hidden?
I agree with your first paragraph; if I'm dropping allot of numbers before the "point", I don't want the sharks coming by later to visit. So hiding the "buyers" ID's is good with me ....There's a difference between keeping feedback hidden and IDs hidden. When IDs are hidden, it's usually because the seller has made the auction that way. A hidden ID prevents the eventual buyer being hassled and I see little wrong with that.
What does irk me though is hidden feedback. If someone elects to have their feedback hidden, then there's something dodgy/illegal going on and I would never ever buy from them. In fact, I think eBay have recently revised their policy so that feedback cannot ever be hidden. :-!
