some people, like myself, do not prefer to hunt from link to link in order to get a view of whats for sale and the price at the end of the road, so to speak. Its a little more effort on your part but personally, I think if you just listed the name of the chip in your post and when someone clicked on the post itself - it would show the chip and your asking price. Of course thats only my humble, and probably lay back, opinion.
Something like this for your Bar West chip.. The ambassador post did not even have a state suggested.
