Amazon offers the Frito Lay Classic Mix Variety 30-Pack for $7.64. Check out via Subscribe & Save to drop it to $7.26 and receive free shipping. That's a buck under our mention from two weeks ago and the lowest price we've seen. (It's $9 less than what you'd expect to pay in a local store now, excluding the mention below.) It includes a selection of Lay's, Cheetos, Fritos, and Doritos.

Be sure to cancel your subscription after receiving your item to avoid being billed for subsequent shipments.

A close price: Walmart charge $7.64 when you opt for in-store pickup.
