My favorite store-bought barbecue was in a bin--Kraft Original. Each 18 ounce bottle was $0.50! I don't know if this is part of a great deal all over for Kraft. But, it cannot hurt to look for it. Oddly, this bin was in the produce section, a bin 4'x4'4' or larger.
Thinking it might be a week from the best-by date, I checked. The date was March 16, 2016. Two bottles plus the one I have at home, just opened, will last me beyond that date.
Have you found Kraft Original BBQ sauce cheaply in your stores? Let me know if you do, please.
