before placing the order, you should check if there are any coupon codes available (i had found one for 10% off)
one thing to note is that the site charged my credit card but didn't send the package until i contacted them a few weeks later ... their customer support was nice though and the issue was resolved quickly.
ETA: i just checked the site and don't see them in bulk anymore ... i had found a 10 lb box of them back then
