Unless you can find hidden discount codes, you're unlikely to change the price of tea on the shelf. But experts Rick Doble, Herb Cohen and Teri Gault all point to three places in the grocery store where you can bargain your way to savings: the meat and bakery sections, and anywhere there's already a clearance.
First, in the meat and bakery sections, sellers are working under the gun. If they don't get rid of an item before it expires, it goes in the dumpster out back. This is especially true in the bakery section, where shelf life might be only a matter of hours. This is why many bakeries and grocery stores already have sections for day-old baked goods. At the end of a workday, consider offering the day-old price for any baked good that would be discounted in the morning anyway. The same is true of meat and seafood (or anything else near expiration).
This works even better if you're willing to buy in bulk. "In the closeout section, look for 10 or 20 items of the same thing," Doble says. "You can almost always negotiate a lower discount."
