It's the same as the name of the site where you serach for the companies with the worst, shakiest service. Sometimes, you get what you pay for. Check out
Reseller Ratings before you order. Go for the ones with lots of individual comments and a fairly high average score. I always scan-read through all the comments, because some people are a bit irrational and give low ratings when they're clearly in the wrong.
EDIT: Also, I always place my first order by phone. If there's no phone number and
street address clearly listed on the website, I move on.
