AH! Then thats a different matter indeed!
But if you want to go that route, folks need to figure out a cost for such an item in the LHS budget, and make sure the budget covers that fee, however you decide to do it.
The recent "Eargle CD" fundraiser netted just over $700 - you can probably only do such a thing 2 or 3 times a year without wearing out the members - and understand that such a constant stream of fundraising (shades of PBS!!) will diminish the likelyhood of periodic non-gifted donations e.g, if you offer treats, people will tend to wait for the treats to give up money. That means the net response changes.
Of course you can sell T shirts and the like - but then your expense goes up (the Eargle CDs were basically a gift - Tshirts wouldn't be)
