Home Depot offers the Ryobi One+ 18 Volt 4.5" Angle Grinder for $29.97. Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with last month's mention and the lowest price we could find by $13. It features a 3-position side handle and type 27 grinding wheel.

Note: This deal is for the bare tool only; the battery and charger are not included.
