Yes, they reset the $1 Spot every 6-8 weeks...it all goes 50% off, then 75% off...then they replace it with new stuff. I *think* it will go 50% off the day after halloween. And there's a LOT of yarn left at mine!
I have a few little friends (ages 5-7) who are learning/want to learn so I plan on grabbing a bunch for them!
