Recently, someone on the list posted that the best prices for AA lithiums was at netphotostore, http://www.netphotostore.com And indeed, their web site lists a price of $2.20 for a 2-pack of the Energizer AA lithiums.... http://www.netphotostore.com/cgi-bin/shop.cgi?pstore&prod_cat=Batteries or http://www.netphotostore.com/cgi-bin/shop.cgi?padd&prod_id=ENB791 So I bit and ordered 16 packs. Just received 8 packs in the mail (16 batteries). The very small print at the bottom of their "printed" catalog says that battery prices are for "single batteries". There is no mention of this on the web site, no distinction between "battery" and "2-pack" in the prices listed. Watch out, F5 owners!
