Can I purchase an Arris TG1682, TG2472, or TM3402 from the COX store?

Hi, I have a VERY simple question that I can't seem to get a straight answer on. Only "that the store can confirm that".

Can I actually purchase one of the modems above (Arris TG1682, TG2472, or TM3402) from the COX store?  Not lease, not rent, PURCHASE as in I own it outright?

I get that the panoramic WiFi is an option (monthly fee). I may, or may not upgrade to it. I don't care about it right now though. 

Thank you for in advance for a simple answer.
