Buy and Sell

Note that for example price for carrots is 3 coins in the Seed Shop.

Now for example lowest price for carrots is 3.36 in the Farmers Market.

First tip: If you need carrots for event or feed, select the place where is lower price. Some times market price is lower than seed shop.
Second tip: If the price is high enough at the market, you can simply buy from the seed shop and straight away sell for profit at the market. Because of the 10% sales fee at the market, note that market price must be at least 3.35 coins to make any profit.
