You guys should check out Minimus.biz if you haven't already. Justin's Organic Honey Peanut Butter in a squeeze package (also Cinnamon Peanut Butter, Almond Butter, Maple Almond Butter, Honey Almond Butter...etc.). They also have a PB&J squeeze combo.

Other interesting things: Mainstay Energy Bars, Mini Tabasco sauce, honey packets, any condiment you can think of, individual packets of OTC medicine, travel size toilitries, etc. I love this site. Also, they're the official supplier of single-serving cranberry jelly to astronauts on the ISS. Who knew? No affiliation, etc.
