Where do you buy your 123 batteries at? I have been shopping for 123 batteries for my flashlight. Walgreen's wants $16 for a pair of them. That seams almost criminal. Walmart wants $10 for a pair. That is still, WAY too much. I found them on the Internet for as little as 83 cents but I am not really fond of handing out my credit card to some company I have never heard of and besides that, there has to be a quality difference between the 83 cent ones and the Duracell's at Walmart. Help, I'm running out of batteries and cash.
