How/Where to try jazz mouthpieces?

I was hoping to buy a jazz mouthpiece for my alto to use instead of my Vandoren Optimum AL4, but I don't have any music stores nearby that carry more than one or two jazz mouthpieces! When looking at suggestions from a few years ago, you used to be about to try pieces from wwbw.com. Now you can't. Would it be a good idea to just order from a bunch of different companies and hope that they come around the same time so I can return the ones I don't like?
