I got 12 of the Eneloop 1500s for <$30 delivered off of Ebay and they came in 3 sealed 4 ct. blister packs, so $10/4 pack shipped. They're legit and have Sept. 2011 date codes on them.
My Costco has the the blue 10 pack for $19.99 plus 7% tax, but I'm not going to renew my membership for those. CVS a big US drugstore chain near me, has the Duraloops for $16+, but even with decent coupons, it's not as good a deal as I can get off of Ebay.
