I ordered my favors from www.wrapwithus.com
My favors were black and white cookies from Angel's Bakery in Greenpoint, Brooklyn. They come prepackaged. I had them leave off their stickers, so I could put on my own (with my colors and theme) which I printed on my inkjet at home.
The cookies were a hit, everyone was asking for extras to take home. Also, the more you order the cheaper they get. Ended up being less than a dollar a cookie(3 years ago)
