Plastic cups; not very glamorous sounding, but trust me these will CHANGE YOUR LIFE. My best friend, Amy (who by the way, introduces me to 99% of what is cool / hot / hip / trendy / important), told me about them several years ago, but my reaction was “HUH WHAT?? PLASTIC CUPS, WHO CARES?” but then, as always, I listened to her (she = always right and in the know), so I bought them. And sure enough, they *changed* my life. Dramatic, but 13 bucks and you get 16 cups; all super cheery and colorful. You do the math, but I think that is a pretty good deal.
