Yeah, it's hard to get around shipping expenses for onesy-twosy parts.
Digikey and Mouser are reliable sources, but not set up for small orders. (I think if you look closely you can find a cheaper shipping option for Digikey.) Adafruit is not unreasonable for shipping. Or Ebay, while slightly more risky, often has people shipping for free.?
Sorry I don't have the part spec's for you.
