Walmart offers the GE StayBright 100-Count 24.75-Foot Constant Mini LED Plug-In Indoor/Outdoor Christmas String Lights in Multicolor for $4.98. (Lowe’s charges the same with free shipping for MyLowe’s members in multicolor or white.) Choose in-store pickup to dodge the $5.99 shipping fee. That’s tied with our mention from a year ago and the lowest price we could find now by $7. They can connect with up to 25 sets.
