I LOVE the Target $1 section. They also have a $2.50 section. They add stuff weekly so you have to check often. I think there was some sports-themed stuff there. Depending on how much you want to spend, you can bundle a few things together in a pail, recyclable bag, or cello bag. For my daughter's volleyball birthday last year, I got colorful water bottles, wrist/sweat bands, socks, and a recyclable bag in that section all for $1 each! I added some other stuff I purchased on clearance at Claire's. Target also has an end-cap in their toy aisle that has outdoor/sports items for a few dollars-water guns, balls,etc. I am not sure what age group you are going for?
