Fast, reliable service, at a fraction of the cost!
The batteries I ordered were delivered in a timely manner, and the price was perfect. I needed a 321 size battery for my watch. I checked with several local jewelers and stores that usually change watch batteries... or at least they did when I was younger. It would cost around $5-12 to change out the battery in a watch. A few stores were now out of business. And the ones that were still in business, quoted me between $50-75 to change the battery, AND they would have to send the watch out, because they don't perform that service in-store anymore. I would have to wait for approx 14 days to get my watch back. Just to change the battery! Unbelievable. I found JewelrySupply.com, ordered the battery, in fact, several batteries, for less than $6, and had them shipped to me. It took only a couple of days. I popped in the new battery myself, have several spares, and saved $70!! I would highly recommend JewelrySupply.com to anyone. Thank you!
