Lowe's takes up to 75% off clearance items, with prices starting from 74 cents. (Most prices are as marked, but some items receive discounts in cart.) Plus, MyLowe's members bag free shipping on most orders. (Not a member? It's free to join. Larger items may incur oversized shipping fees.) A couple of best bets:
Kichler Lighting Covero 1-Light Square Vanity Light for $16.23 (low by $7)
Allen + Roth Elham 3-Light 9" Aged bronze Bell Vanity Light for $51.98 (pictured, low by $21)
The dollar store is the most amazing place to find bargains for certain purchases. Yes, even pregnancy tests.
