Prices vary as there are a lot of deals and such. The standard prices will probably be about the same. So check the "Good Deals" forum and see if maybe you can get free shipping or a percentage off or a free product or whatever. Or, if you want to try a few things, see if you can find a kit that has stuff you like/want to try and get that. You save a lot with the kits.
There's some place (do a search here, 'cause I can't remember who does it) where you can order like 2 oz. samples of AIO and SG, though. That might keep the shipping low. Otherwise, I'd say buy the 16.9 oz and some other stuff you're interested in because shippings the bear there. If you're interested in AIO, then I'm pretty sure you'll like it enough to find some way to use it. It's easy stuff to use and does a nice job.
