I'd be cautious if I were you. I learned the hard way, from getting burned by a discount place. At $5 a syringe, they are cutting corners somewhere...trust me. I got the $5 each deal, for ten, from sporestore.com. Innoculated 40+ jars with not a single spot of mycelium. Not a single spot of contam either so I know it wasn't from improper proceedure.
If you want a list of vendors you can trust, visit shroomery.org. My personal favorite is RalphstersSpores.com.
I wish you luck, and would definately keep your fingers crossed. Keep us posted.
