Keeps the ads up, may take time. There is some good advice above.

The only other thing I suggest is "networking." Not internet type but the type where you talk to people and ask them to talk to people. Tell them you want one before Christmas. I find more pins just talking to people.

I got a lead on my Blackout and Gorgar while doing the paperwork to buy my current house in 2004. I was talking in the office about what room was going to be for the pins. The lady doing the paperwork overheard and asked if I wanted more. I went and looked and bought at a great price.
