I dunno.

Ever been to a flea market? How many of those people are paying business taxes?

If you are selling used low price items they tend not to bother you any more then they go after garage sales.

On the other hand if you are selling new or high value items they will come down on you like a ton of bricks.

The line between "Hobby" (not taxed, mildly regulated) and "Business" (taxed and regulated up the wazoo) generally has to do with how often you sell and at what price.
