If you pay my expenses, I'll be thrilled to show up. The AHA doesn't do that, though.
I don't know of any shops that give discounts to members, but that doesn't mean there aren't. If you find any that do, be sure to, let us know. Kathryn might know if there are...you could try sending her a PM.
I like both of your suggestions....implementing them could be an issue, but we'll definitely keep them in mind!
