Although they appear to have quite a few things, they did not have a very large selection of watch style batteries. I came in looking for a battery for my wife’s calculator that she has had for years. It takes a CR2029. I guess that battery is very unusual, or maybe even nonexistent anymore because I have not yet been able to find it. The gentleman at the counter tried to be helpful and even started explaining what the numbers indicated, but still, no battery. I will try them again in the future and maybe they will have some of the other batteries and lights that I will need, we all know that in todays tech world that we all go through a lot of batteries. On a side note, please recycle all of your batteries properly. :-)
