According to my Merchant Agreements (with the credit card folks) I must clearly state my return policy. Obviously, that would be "all sales are final." So we must make another sign, by contract if not law, to that effect, conspicuously displayed in our place of business. I cannot  say "If you bought it, you bought it, now take it home and hang it up or give it to Uncle George if you tire of it" so we're doing a tiny version of the GPG outside sign that says "Love your Art/sales are final." We had "all sales are final" but the ll in 'all' really interfered design-wise, so "sales are final" is the way it reads. We'll hang it up in the office corner, under the painting behind the computer. Which is where folks will stand and where their eyes will be oriented whilst I'm swiping their credit cards so I'm pretty sure they won't miss it. I'm also expected to have my return policy written in quarter-inch letters on their hand-written receipt so I think I'll have a stamp made up for that. 

All these rules. You should have seen the Discover Card Merchant Agreement. No wonder they sent it on a CD. 125 pages.

OK, I'm posting this now and downloading some pictures. Come back in a little while and you'll get a preview of the GPG outside sign! And maybe some other stuff as well.
