I've been buying my Lithiums on Ebay mostly, but I recently discovered, at Wally World at least, that their prices have come down. A 4 pack was 9.99 & now, I've been buying packs of 8 for $11 something. I haven't seen anyone mentioning this, so I thought I'd throw it out there. I dunno if it's just our Newark store, but it's certainly worth checking them out.
