In the past, a few folks on the forum have sold off “Mystery Boxes” of flat-rate USPS mailers, with the idea being that recipients would get a random assortment of cool things in return...for much less than those things would cost on their own.
I am trying to gauge whether or not there’s enough interest for a similar idea to still work. If I were to cobble together some boxes of this type...what would you want, what would you want to pay, etc.?
