I have made a few sells that needed large or medium flat rate boxes. So I thrown in a few on top and bottom. Freeies and fill up the box. They are were about what I sold them. Yankees Celtic Hockey (find a couple after I sent them off)
I'm with wbakero1 on this one. The show I did no one even asked about the ones I had. (Bronco's super Bowl win)
I know a guy that 90% of what he did was magazines. I got several of ones I want from him. He always keep and eye out for any I need. I still think there is 2 more that I need. He always said it paid for the table most of the time. He was retired and enjoyed doing that. He passed away a couple of years ago. Who know what happen to his invertory.
