Yes, exactly. If six people bought things per month, I'd just keep the shop as-is, because expenses would be covered. (Well, 12 people if they all bought buttons, because I just couldn't see putting $1 markup on a button.) But things haven't worked out that way, ergo the decision to scale back.
I suppose if someone else finds the very existence of the shop amusing enough to pay the $6/mo tab, we could work something out. That someone would then be able to buy any item at the base price, meaning $1 off the list price, of course.
I'm sure there are plenty of people out there for whom $6/month is an amount too small to bother worrying about, but sadly, I'm not one of them.
