The cheapest place to buy bananas is Costco. A pack of nine bananas is $1.29, or 14 cents per banana. They are very green though. Will they ripen nicely? It's a gamble.
The next cheapest place to buy bananas is at Trader Joe's. At Trader Joe's a banana will cost you 19 cents, regardless of size.
At Berkely Bowl a medium banana is 25 cents (based on a 69 cents per pound price).
At Grocery Outlet, seven bananas in a bag is $1.99, or 28.4 cents per banana. I know it's hard to believe, but the almighty Grocery Outlet is not always the cheapest!!
You know what else isn't the cheapest at Grocery Outlet? Raisins. Today I could have bought a two pound bag of raisins for $3.99 at Grocery Outlet but I didn't because raisins are only $1.25 per pound at Berkeley Bowl! But this is not a post about raisins, it's a post about bananas. Try to focus on the correct subject, please.
At the Quick Stop gas station, one banana is 75 cents.
