One thing I learned recently is that you should NEVER ever buy batteries in a watch store.
Know those small, round batteries for watches, calculators and other gadgets? I needed two LR-44s for my daughter's calculator, and bought them at a watch store in a mall. I was surprised that they cost 150 pesos apiece. I thought they'd cost less than a hundred bucks.
I recalled that I also had the battery for my running watch changed maybe a couple of months ago. If memory serves me right, it cost around 200 pesos, including the watch repair guy's services. The watch (a Suunto T3) was difficult to open, and the serviceman struggled for some minutes before he could pry it open and put in the fresh battery. The watch needed a single round battery, so I thought that, surely, 200 pesos wasn't just for that one battery, but also for the serviceman's efforts in putting it in.
Anyway, I happened to pass by a photo store that also sold batteries, and I asked about their prices just for comparison. Their LR-44 was 60 pesos apiece, versus the 150 pesos I paid in a watch store. The bigger round battery which was used for my Suunto watch (I forgot the exact label) was merely 75 pesos, compared to the 200 bucks I paid.
So there, I learned my lesson. Never get your batteries in a watch store. They're way overpriced.
