Seems very unproductive not allowing everyone to see the offerings and probably could have gotten some new members if they could only see what you are selling for them to purchase.
True enough for Stu's original links, but you do have to actually be a member to order them.
This link seems to show the small thumbnail, but it's not any bigger than the graphic posted above. {edited since Stu has better links below}
I do agree it would be helpful if the TCA site maybe did a simple one line description for each so people could know if they were interested (like what gauge each car is) before joining to actually be able order. But then again, I am not a volunteer helping to organize this, so I'll not throw any large stones.
