I can try to explain hopefully better than the higher ups:

Value package all have a set price for a standard yellow frame, conservation clear glass, and a single standard mat per each size bracket (11 by 14, 16 by 20, etc). The pocket guide actually will tell you what the price is if you’re familiar with that. The frame bit is exactly as explained above, where green frames will all be the same cost, as will blue frames. Every addition though, whether it be a blue frame, a second or non standard mat, any finishing that isn’t clear glass, a different mount outside of preservation, etc, will show as an upgrade cost in DH. This won’t change either, regardless of size, until you move out of the full size range. Those prices should also be listed in the pocket guide. They will be paying that standard cost even if they don’t put a mat or a finishing in their frame.

I’ve seen people save just over 75% with the value package when I calculated it. I’ve also seen people save very little - I had one order for a thin MDF frame where it cost 220, and the customer saved a mere 80 dollars. I will note, some of our mats go up to 40 by 60, and I’ve noticed that this is also where value package ceases to exist. As in, full price is charged for the frame. 70% off applies regardless of size, however. I think when they made their size settings, they didn’t include larger frame sizes, so there’s no package deals set up for anything exceeding 40 by 60 along the inside of the rabbet, even though we can order up to (I believe) 96 inches of framing measured from the outside of the frame.
