Query: Best deal I have ever found on LR44 button cells!

These button cells are the best quality for the lowest price I have ever seen. If I go to a retail store locally, I pay *the same price* for ONE battery as they cost between 5-10 bucks EACH. So I can get 50 for the price of 1?! I will never buy a battery at a retail store again. Who in their right mind would pay 10x as much for the same product. (1000% markup! Retail average is %50 markup, I am a small business owner.) I didn't test every battery, but I did a random sampling of about 10 of them, they all came back at an average of 1.556 volts. Perfect, exactly where they should be. I am so impressed I will be a Amazon.com / PlexSupply customer for life. Thanks for the great product!
