I'm using autofacebook with zen 1.5.1

The plugin is working great except extra zeros are added to the prices like $949.00000
heres a link https://www.facebook.com/ntsolutionsllc?ref=hl

How do I get the plugin to include the discounted price and fix the zeros or just not include the price at all?

I also want to use the autotwitter plugin how do I install both plugins?
