Ending today, Macy's offers the Black + Decker Lithium Handheld Vacuum for $19.99. This $10 mail-in rebate drops it to $9.99. Choose in-store pickup to dodge the $9.95 shipping fee. That's tied with the price we saw on Black Friday and a great deal for such a handheld vacuum. (It's a current low by $15.) It features a lightweight design, wall-mountable charger, and washable bag filter.
