Some wineries shut down after the big Thanksgiving weekend. If they can't ship, what can they sell? But there is a lot of money to be made between Thanksgiving and Christmas.
It might be too late or cold to ship, but these three ideas are proven to work and have the added bonus of being popular with office staff and corporate gift purchasers. Sell one, sell 100, you don't ship until after the holiday and you get the money upfront.
