Where can I buy diet Shasta grape soda in the San Jose, CA area?

I haven’t seen it in years, and dang it I want some! I will be shocked and amazed if I get an answer

Yeah i would try a smart and final good answer.
Winco is a pretty neat store, I don’t know about shasta, but they have reeally cool and random products and a HUGE VARIETY.
