Joe,
$1 USD is pretty typical for retail, not a great price. The online suppliers are great, but its best to order in bulk to offset the prices of shipping. For one snake you will have to vacuum seal the pinkies to keep them from going bad in your freezer.
Steve,
Apparently pinkies are not affected by gas for some reason. I haven't tried this for fact since I'm amongst the population of wackers

I have been told by several sources though, some of which work in labs.
