anon for this:
As a suggestion: If you are in the store anyway, you can ask the manager to match the other non-jewish store’s advertised price.
I have not done this for food (B”H the prices are OK here, and for many things the Jewish stores don’t carry the brand/type we like), but I have for other items, sometimes they matched & I bought and sometimes not.
cantoresq: Goldbergs in Boro Park (In Town 🙂 has a “Stimulus Special” (I think thats what its called), and I think (seems to me) their prices for Purim stuff are even better than last year.
