I know that a lot of collectors purchase discontinued Lego sets on eBay for two, three, or four times retail. I've also had buyers purchasing these sets for their children. Recently, I had a buyer from Italy purchase some of my sets for two times retail with the intent of reselling.
As sellers, I know that target market is very important, as it determines the sustainability of secondary market prices, and I'm interested in hearing your thoughts on what types of buyer are generally behind these purchases. Thanks for your input and ideas.
