Check your local Walmart for Red Heart yarn clearance. Many in my area are marking down some colors of Red Heart Super Saver to $2 a skein and the Red Heart Love to $3. The price online for these at Walmart's site remains unchanged. You'll need to hit the brick and mortar to see what's being clearanced out. Be sure to grab what you need to finish up your projects! I was told by an associate that they're making way for Fall colors and thicker yarns.
Some of the kitchen cotton yarn was also clearanced, some as low as $1.
