I also had a wholesale account with Light Impressions, and when they fired my account rep and became just another idiotic corporation run by bean counters, I, too, ended my business with them. The fact that I rejected a large percentage of the frames they cut for me made it even easier (QC went waaaayyyy down). I say screw LI for good.
I now get my frames from Documounts and all other materials from United Manufacturers. For the person who required a West Coast supplier, UM has a warehouse in Las Vegas. Shipping costs even for full cases of 32x40 boards is very reasonable.
Bye bye, good riddance to Light Impressions.
