What are the average road side shop rates in hay day?

So I play hay day on my iPhone 4s and I'm at like level thirty and I need money to get some stuff repaired. I want to know if there are any good sites that tell you how much to price your items in the road side shop? I know average rates for the simple stuff like eggs and wheat but I need to know about the pies and cakes and such…

I'm using this hay day hack:

it works perfectly so far
