Non-PRO Greek to English Other General / Conversation / Greetings / Letters

Again in a company's letter to a security group, I am not sure I understand xreono correctly in this context:
τα ειδη που πηραμε στις τιμες που τα χρεωθηκαμε...
η απαντηση ηταν στο 1/3 των τιμων χρεωσης.
What does pou ta xreothikame mean here?
And does anyone know what timi xreosis is in English or German please?
Many thanks for your help,
Tanja
