I got to thinking about this because I tried reaching out to a lube company regarding where I could find sample sizes of their product. I emailed the company twice. I wrote the e-mails very professionally and addressed them "Dear Sirs or Madams." Both of my e-mails were ignored.
The next time I went to their website, I was going to try to get their phone number so I could call them and ask. I saw that the samples that I was looking for were now mysteriously available for purchase on their poorly designed and sllllooow website. Annoying.
I've heard through the web that FunFactory and JimmyJane are great to deal with and from what I've heard Jopen is a hit-or-miss.
