He didn't give you a simple answer because there isn't one. And you have to understand that markup is honestly something you should just deal with. Because look at your everyday shop, yes the stuff is expensive and it makes it look like you are getting *****, but you have to understand the cost of running a shop. You have a possible mortgage, utilities, employees, insurance, etc. There can be alot of overhead for a shop and the owner prices his stock accordingly. I know a shop here in evansville sits in a expensive piece of land, but gets alot of traffic. It's not big but the overhead of running the shop and the price of rent is what kills them. On the upside, they get alot of business for being where they are. So please before asking a question like "how much of a markup is there" think about all the factors into the markup.
