If you buy the $3.00 samples, they automatically bill you up to $9.99 per 1/2 pound package (by default you ordered 3) every 6-8 weeks. This info can be found in the Terms and Conditions sections. BAIL!
just call the number and cancel your subscription. I did it last time and there was no problem at all.
