They also have their Holiday Time brand Red LED tape Lights (240 ct, 19.6 ft) 50% off, 9.92: https://www.walmart.com/ip/Holiday-T...-Wire/53082540 I might use for some for a circus theme.
Might still go down in price, not sure. But if you need the lighting for set up this fall, might be a good deal now as these lights will be back to full price before then. All have a Free Store Pickup option.
