Marco should buy as well as sell

[Apple Pie]

I have surplus stuff, all kinds of things: artefacts, supplies, food/gold/oil sometimes, fragments, resources, trade goods etc. it varies over time but I always end up with too much something or and overfilled something. I think Marco should offer to buy things from us very cheaply. Would love to off load a shed load of gold for one single token or a lorry load of trade goods for a few crowns. This would really help balance the game as it is frustrating to just keep seeing things are full and can no longer be collected whilst other things seem to never be available.
