I'm new to this site so i don't know the proper formatting for questions here.
My friends and I were having a debate whether or not saying "I ordered it offline" was a correct way to say "I ordered it online" or "I ordered it off the internet". It seems as though its more of a preference however are they all grammatically correct, and which one do you use/hear more often?
UPDATE
I didn't make it clear enough, when I'm referring to "I ordered it offline" I am referring to ordering something online or off the internet
