Every so often I put together a grab bag that contains ???????????????? at a set price. Sometimes there are 100 available, sometimes there are 10.
*If you've never had the chance to grab one of these, basically I make A LOT OF STUFF and am kind of a hoarder of other people's stuff and basically I just have a lot of good surprises and every so often I force myself to say goodbye to some of my treasures. I used to do a subscription club for a few years and this is sort of what that morphed into, since it's a bit more sporadic and also you don't have to pay upfront and then wait all year for your mail.
