When my printer failed in a manner that left it beyond economical repair, I found myself with ten new, unopened toner cartridges that I could no longer use.  After a bit of on-line research, I determined that the buyback program would be my best bet for recouping part of my investment in toner.  They promptly provided me with a reasonable offer, and sent me the offered check immediately upon receipt of my toners … a pleasure to do business with them!
