Iconikal via Amazon offers the Mastrad TopChips Healthy Chip Maker for $8.35 with free shipping. (Non-members can spend $49 to bag free shipping; otherwise, it adds $6.74.) That's a buck under last week's mention and the lowest total price we've seen. (It's a current low by $2, excluding the mention below.) These microwavable chip-making trays are stackable up to three high. Deal ends May 5.

A close price: GearXS offers it for $8.78 with free shipping via coupon code "DN-21."
