Selling things/food in the game (Graveyard Keeper)

The better your relationship with a particular character, the more variations for trade opening.

Sales is difficult, for example the bartender buys the wine with a silver star, and the dealer only with gold. The dealer can then sell silver and gold bullion. The blacksmith can sell the first tool (rusty), iron ingots, nails and elements. The logger can sell the axe on 2 levels, the farmer vegetables of the lowest quality. The fisherman at the lighthouse, you can sell some types of fish. At the same time, the more we sell the more the price falls. A lot of products (ready meals, beer, spirits), which I still don't know who to sell

Guys, I have a blacksmith does not sell for years, just no button to confirm
