Their $1 spot merchandise is 50% off right now, and they have zippered lingerie bags in two sizes…great for felting! 
I’ve heard that some stores have $1 yarn, needles, and patterns too! I haven’t checked mine out yet though. I think it’s just acrylic, but that’s still a good deal!
i’ve seen their little kits on clearance.
Hey…WOOHOO…it all went 75% off today! So 25¢ for felting bags! Go get 'em!
