greta service
I have done business with you in the past and this time it was excellent service also. Telephoned, spoke to your rep and he helped me order what I needed since I had forgotten the name of the cartridges. He walked me through it, said when I should receive it, placed the order and within several days it was received. Can't ask for any better service than that, Thanks!
