Request regarding the market place.

I keep on getting too excited when I'm seeing a good deal in the marketplace to then find out that it's in another country and that the shipping + taxes makes it worth to be the same price as whatever.

So I was thinking, maybe to make it compulsory that the seller either puts (US) or (UK) or whatever their country code in the thread title so that buyers like myself don't get our hopes up lol

This is an old chestnut 'round here. The usual reply is that some people like to hide where they live. Is too much to add you are in China, USA, UK or wherever?
Looking through the 'For Sale' ads I skip those that do not specify 'UK'
