I made mention that I recently bought a bunch of Jason Bay cards form ebay. For $22 shipped, I received 100 different Jason Bays to add to my collection. Of those, 24 were new. The other 76 have been added to my Nothing But Bucs binder where I keep a bunch of doubles of Pirates in numerical order.
As I become more and more conscious of my ebay spending budget, I've found that these type of lots offer a much better value to my collecting needs. Often I would just buy individual cards then overpay for shipping, but with patience, being able to grab lots like this when they present themselves are preferred.
