Can't join in this time around, but Amazon has some Bento stuff (Based in Seattle, so totally American).
I've also found http://www.vitacost.com/medport-fit-and-fresh-kids-lunch-pod
to be useful (If you sign up on Vitacost you get $10 free to spend, then just pay shipping. If you don't sign up, it's cheaper on other sites) for Bento.
I've also found lots of picks at the Dollar Tree. I got a pack of like 200 in like 5 colors with hearts on the top just the other day.
And, I get my tiny spoons from my favorite Easter candy. Milka chocolate eggs come with 4 eggs and 2 tiny spoons. I always just use one and wash it, then save the other. If you know anyone who works at Baskin Robbins, you could also probably convince them to smuggle you a few of those pink spoons. They are pretty awesome.
I hope that gives you guys a few ideas.
