Good deal on wristwatch batteries

Every year that passes, I seem to have another device or two that use "coin cells". I know how to replace the battery but I really don't want to truck over to CVS or Walmart and get one of unknown quality for $5.00 or more. I like the idea of a package of five fresh Maxell for $2.65 including shipping showing up in my mailbox three days later. For several years now, thebatterysupplier has been my battery supplier.
Excellent product!

I have a ton of watches. I wasnt using them because they all need a battery. Every time I take it to have a battery it was $10.00. So I said there has got to be a better way. So I googled watch batteries and Thank GOD I found you. GREAT
Good fresh batteries 391, 377 and 364

Good selection of batteries considering the number available. Recently manufactured will provide maximum life. Only complaint, delivery was a week later than estimated.
