I've used cash for all of the above except buying a bus ticket b/c I don't ride buses. Even fast food places have credit card swipers. Hell, Sonic has a credit card reader at the drive up menu. And yes at bars, you start up a tab on your card and it only gets swiped once, not for each drink. Not a big deal. I hardly ever use cash; I don't think there are many places at all were credit cards aren't an option anymore except maybe a vending machine. I even use a credit card to buy things at Goodwill! Us young'uns don't use cash for much anymore. I typically don't even carry more than 20 dollars. However, I am not disputing the point that the US should differentiate the bills to be discernible for the blind. That's fine. Just disputing your argument's basis.

If you really want old Avalon Hill games and other such things, you could look here: http://gamersalliance.com/. However, you won't find the good stuff cheap. Also, there is a membership fee required to get access to the catalog. They have Avalon Hill, TSR, and others, depending on their supplies at the time.

So, really, I suppose that site is only good if you have quite a bit of extra money to throw around, but it is the one I found. eBay is often a better (and cheaper) alternative, though.
