Can I say "I got this bread at woolworths" instead of saying "I bought this bread at woolworths"?

The difference between get and buy. I always use the word "get" instead of "buy", I thought they were the same meaning in terms of buying stuffs

won't pretend to be a boffin, but the word "get" is to acquire more or less any old how - eg in theory, to say "get" could even mean you stole it from woolworths. "buy" is a whole lot more specific, ie to acquire something by parting with money for the item, so "buy" or "purchase" would be preferable when it comes to shopping.
hope this all makes sense!
