I'm pretty sure that's normal! It seems like a very small boutique operation, so I think the time lag is due to labor issues.

Most people don't actually order their samples from the Lab, as far as I can tell! You can swap other folks for ones you want to try, or buy them on eBay or here on LJ at the various BPAL communities, and then buy big bottles directly from the Lab, when the 2-month wait isn't as awful. :)
