The first thing that caught my eye was this centerpiece kit. The bottom and top are 2 different vases that can be used together or separate. You can put fruit, candy or ornaments (as I now have in mine) on the bottom and flowers in the top. Kind of cool! The set is $40, but they'll likely go on sale after the holidays so you may want to check back. One note... they are bigger than you think. I'll take some photos of mine and upload them once I have normal internet next week.
I also love these for people bringing purple into their event:
