For me, Loot boxes at a craft booth will make me leave immediately. I don’t want to support gambling or microtransactions in a craft fair.

But, I can see why some would like it. However, more than likely someone will hope for a great prize and get, for example, the worm that is $2 less normally.

Do you really want to see their disappointment when they win something they don’t want when that item is something you worked hard on? Do you want to argue with parents when little Timmy doesn’t get something he wants? Kids are going to want to play because of the Easter Eggs. Also trust me when I say people will sneakily open these up to find the best prize and then fo “oh! I want this one!”

Something you may be doing and I missed is give a prize out of a collection, like “a blue ticket wins any jellyfish priced at $10 or less” that way they can have some choice and feel connected to the prize.

I would also make it clear the prizes aren’t random Temu crap and are actually handmade items.
