I love cute containers for food and favors. They're the type of thing you feel really bad about throwing away. It certainly adds a little to the budget but if you can afford the extra touch it really does pay off aesthetically. Check out Garnish for cute packaging and also for ideas on their site. I have a feeling that some of the things they sell could also be found at restaurant supply stores or stores like Smart and Final (if you live in CA, NV, or AZ) but it's definitely a cute site to check out. I love the berry boxes (top left image).
