Brad's Deals Editor Marisa,
These Better Homes & Gardens 20-Count Outdoor String Lights drop from $19.99 to $12.78 at Walmart.com. Shipping is free when you spend more than $35. Otherwise, it adds $5.99. This is one of the lowest prices we see on patio lights from any major retailer each year. The light strand is 18.7' long. You can connect up to three sets together. Sales tax is charged in most states.
