You meet a local villager on the bridge on his way to market. He is walking with a bag of wool over his shoulder. Offer to buy it from him. You can sell it at the market.
Your family have some sheep and cows. You could take some of their wool and skins to market.
Which card will you play?
Don't be so hasty. Look in your purse. You don't have enough money to buy those bargains and no goods to offer in exchange.
It may be an adventure but it will not make you rich.
