Some of the most rare star wars LEGO Sets can go for 2 to 3 times as much as their initial retail cost. This is because the LEGO Group stops production of a LEGO set after it has been out for a certain amount of time. This creates a demand for LEGO Sets that sold particularly well or become more popular than others for whatever reason.
This creates a market for rare Star Wars LEGO Sets on places like eBay or other auction style ecommerce sites. These auctions can oten turn into bidding wars with the final price ending really high. For this reason many collectors and would-be resellers buy at the retail prices and then hold onto a Star Wars LEGO Set for awhile until it is no longer available from LEGO or LEGO retailers. Then they can sometimes turn a nice profit from these discontinued rare Star Wars LEGO Sets.
