Yeah, I just ordered them for $2.99 last week as well - didn't realize why the price was so low till I went back today. I guess it's a closeout.
I love these two colors together (I guess a lot of people do!) - am making little sweater jackets for my sons - one was going to have lettuce as the main color and pool as the contrast, and the other was going to be vice versa.
Let me know if yours doesn't work out and you want to sell any - I would pay full price!
