NERD's lemon pastel grading scale

Does anyone know what the grading scale is that NERD uses for their pastels? I dropped them an email inquiring about it last week but never got a reply.

Good looking = $$$$
Average = $$$
Regular = $$
Poor = $

LOL no I don't really know what they do to grade them. Be paitent with them I know they have allot going on right now and their behind on Emails and what not. You could always call. :D

Yeah that's what I figured. I usually try to avoid calling people when I think they're busy, I always feel like I'm being a nuisance. ;) I only asked here because I thought someone might know off-hand and it would save me and whoever answers emails at NERD some time.
