There are two types of antique dealers in my area:
Ones that check the price of everything to see what it goes for on Ebay and price to match.
Ones that just put prices on stuff based on what similar items have sold for in their booth.

The first type tend to have overpriced wares. They seem to find a razors of the same brand and match their price to the highest selling prices on Ebay. They don't understand that there can be some big differences between two razors of the same brand. Sometimes they can be talked down on the price, sometimes not.

The second type tend to have some great deals on their razors. I have gotten to know which dealers are of this type and I visit their booths often.
