Spring Hill Nursery is offering $20 off a $20 purchase; click here for details. I've never used this site, but I've seen other blogs mention other deals offered and they really do come through for you. Only one offer per household and you pay the shipping. And don't forget to sign up for their newsletter.
I think I'll look around on this site tomorrow and perhaps pick something out. The girls and I picked up a $1 box of "bird and butterfly" flower mix from Walgreens and we plan on sprinkling that in the backyard in a day or two. Way in the backyard. Little girls need room to run.
