This afternoon I got a definitive answer on when you do or do not need permits to buy and sell stuff on Ebay from your house:
(scroll down if you're curious about the process for properly licensing a home-based Ebay business in Amherst).
So "engage in the business of" means "sell for a profit." So I'm OK, as long as the stuff I sell on Ebay sells for less than the price I paid for it. Good to know. I wonder if I'm allowed to use inflation-adjusted prices (if I sell a Star Wars action figure I bought for $3 in 1977, and sell it for $25 in 2007...)
I feel a little dirty. Just the other day I implied that Larry Kelly was wasting state employee time filing ethics complaints, and here I go and cause who knows HOW much town employee time on this one little question. I didn't mean to; I expected a quick, simple answer like the one I got from Northampton...
