Batteries, coffee pods, wipes, trash bags, dishwasher tabs, gum — if it's sold by the each, this is the math that finds the real deal.
Prices change fast — YMMV.
Pre-filled with AA batteries: same brand, and the small pack costs ~42% more per battery. That premium is what this page exists to catch.
PriceXray runs this math automatically against current Amazon listings — every result sorted by price per count, coupon math included. Add Walmart, eBay and Google Shopping to the same search with one tap.

Batteries are the classic: pack sizes run from 4 to 100 and the per-battery spread is routinely 2–3×. (Also worth a look: rechargeables — the per-cycle cost embarrasses disposables if you actually recharge them.)
Coffee pods hide their math behind box sizes of 10, 24, 32, 72, 96... At 30–70¢ a pod, the difference funds a lot of actual coffee.
Wipes, swabs, tabs, bags — the boring aisle where "family size" and "value pack" are vibes, not promises. The count is on the label. Divide.
We track count-based staples monthly across retailers — current leaderboards and whether the bulk pack is actually winning:
