BAD NEWS: The Halloween postcard sets are officially sold out and Topps does not have any plans for a waiting list this year.
GOOD NEWS: For anyone still looking for a set, I've had a few forum members contact me and offer to help out their fellow collectors. Keep in mind, I can't guarantee any arrangements of these transactions and you will need to negotiate with the seller regarding price, etc. But if interested, send me a PM and I will forward your information as sets become available. Your information will be relayed on a first come, first serve basis until Halloween (Monday, October 31st, 2011).
UPDATE: If anyone has an extra set that they'd like to offer to sell or trade, I have a few people still looking for sets. Remember, these are for forum members, so please don't PM if you're just looking to flip sets.
