My mom bought this fabulous cupcake tower (on sale for $10). I've used it so many times. I even put muffins for showers and corn bread cupcakes for entertaining.
I've found so many sites for cute cupcakes. Check them out http://www.wilton.com/ and http://www.bettycrocker.com/
Total cost for my cupcake tower $2!! I watch the grocery ad's and purchase the mixes when they are on sale for $1. Then when it is party time I pull the mixes out of the pantry.
Extra tip I substitute applesauce for oil. Keeps the cake moist and saves the calories!
