I recall reading one or two posts from folks still looking for those elusive (and discontinued) Little Nippers.
Just yesterday, while touring Portland, Oregon, I saw about 10 Platypus "Beverage Bars" at a local outdoor retailer called "Next Adventure" (nextadventure.net.
Each "bar" consists of four Little Nippers plus a carrying case — and sells for $14.95 (no sales tax in OR). While that may be more than you need, I am sure you can sell the excess pretty easily.
Next Adventure does NOT sell online, but the website provides contact information for phone orders.
