Anyone know of a cheap place to get those Thill batteries for making lighted nocks? Or the CR 435 lithium? I've seen them on ebay coming from China. I was hoping there was some place here to get them cheap. I did find the Thill batteries at Gander Mountain and Cabelas for $4.99 each. Isn't there some place cheaper? I haven't found them at the local Walmarts.
