Walmart offers the Clear Innovation Solar Powered LED Lighted Landscape Edging, model no. LEDEDGE100, for $28.50. Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our March mention and the lowest price we've seen. (It's a current best by $10.) This set includes 36 interlocking panels for 18 feet of edging. The LEDs go on and off automatically.
