What is a set?

What is a set?

I have discovered the wonderful flavor of Shallots. I have also discovered that they cost $4 a pound at the grocery store and unfortunately, a pound of shallots doesn't seem to go very far. My question is about sets, onions and shallots seem to be able to be grown from a set. The problem is that I don't really understand what a set is. Do you only get one shallot/onion per set? I've seen Shallot sets at a few places around town and am trying to figure out how exactly they work. If I'm only going to get one veggie per set I don't really want to pay $2 for 8... that'd barely make one dish. Also, is it difficult to grow shallots from seeds? Thanks for your help!!
