@Cord - tried to do a testimonial/review on Trustpilot, but got an error message when I submitted it - so I'm not sure if it went through or not. If you didn't get it, let me know and I'll do it again :)

Also, most Zen Cart Mod developers have a donate button either in the Mod's admin area, or on their website. Typically, this is a Paypal button which allows folks to donate to the developer for his/her work. I don't see one on the mailbeez website or in the Mod's admin area.
