What price can I expect to buy/sell a wine for on BordeauXchange?

When buying and selling through a traditional merchant you can typically expect to buy the wine above the market price. Then when it comes to selling, you will receive 10-15% (or more) below the market price due to the industry standard 10% sales commission. Most trades on BordeauXchange are executed within 5% of the market price, providing much better value for both the buyer and seller.
