Ouch. You severely over pay then. This is my price chart on craigslist and the louisiana reptile groups, and keep in mind I'm just giving you an idea, as to maybe in one of the local groups a guy does like me.
Though I'm likely going to adjust the price a tad bit more for single and 10+ each, that way I don't have to really open packages and instead can sell the entire package. What I do is order $300 worth of stuff, and divide shipping among everything. If I go up a dollar more per package which I'm thinking I might do, that would help me bring down my cost.
