I'm glad you got such a good steal! But I feel kind of bad for the people who bought the figurines and kept them in the original packaging all these years, just to sell them for pennies on the dollar at a yard sale.
When I worked at the big chain bookstore and we started selling these toys, I couldn't believe what people would spend for them. My co-worker would buy half the stock! "These POP Vinyl figures are going to be worth so much someday..." Three moves and three years of storage rental costs later, he's still waiting.
I know what you mean. Last year, I sold all my original, unopened Austin Powers figures that I had owned since the late 90's, on our own garage sale.
