I've seen them in my Disney store, which is in a *sings* little town, it's a quiet village... so I'd definitely check that out just in case they're still on the shelves. It's a 20th Anniversary edition so I'm not sure if it's new enough to be in the smaller stores still, but you never know.
And grr, they don't seem to have it on Amazon. And sold out on the Disney store web site. >.< Checked Ebay as well and they don't seem to have it. I think your best bet might be to shop around the Disney stores in your area and see if they still have some in stock.
