wow. who knew so many people wanted die-cast cars and trucks...

This is a tangential thought and may not be useful to you: I've often thought it would be cool if a person with particularly good taste made a store where they only sold four or five items, but they were items that I could reliably know where quality and the kind of thing that actually results in a better quality of life. Some of the work I would pay extra for is not having to do the "shopping" part. When I get on Amazon it's a pain in the ass to figure out what is the "right" version of the item I'm looking for. A shop that had four or five very high quality household items that were rotated several times a year might be an interesting way to attract stackers -- especially if the shop developed a reputation for listing good items that were hard to find.
