Plain butter is good too haha

Didn't say it wasn't.

Plain butter typically costs more than peanut butter, unless you meant to say margarine which is cheaper. (Regular butter, store brand, on sale 1lb ~$2.50; PB on sale, store brand, 1lb ~$2.00; Margarine, giant tub >1.5 lb of just about any ~$3)

We'd buy plain butter/margarine because it was more practical than peanut butter. With butter you can use it for other things. We couldn't afford the bonus of peanut butter.
