Being that I have no hobby shops close by, I do look at ebay on a regular basis and sometimes just have to laugh at some of the items people are trying to sell. Some of the items are nothing but model railroad junk. Many of these items they are trying to sell I wouldn't even throw in a junk box, it would go right in the trash. Then there are those trying to sell at or above retail price, and then expect you to pay shipping on top of the high prices. Take for instance a vehicle. They ask full price and then want shipping on top of it ???
I do look for code 70 track and switches, mainly Shinohara, and I am well aware of what it retails for, but I haven't paid any where near retail price yet. I know how high I will bid to "get a deal", but I have my limits.
There are then those who claim to have something "rare" and go a little overboard on their asking price, but I guess that there are those who have more money than brains that actually pay the over inflated prices.
Deals can be had, but you really have to pay attention.
