Although they have a small selection, Label Peelers is pretty cheap. About $12 per case and was $20 FedEx Ground shipping. I used Packaging Options Direct once, and while I paid $6 a case, shipping was astronomical ($50).
If you have a winery nearby, consider going there. Most would be happy to give them away since they just recycle them.
If you don’t mind doing a little work, check your local winery. Where I from, they can’t re-use the bottles they consume for their wine tasting. I get once used bottles for $5 a case from my local guy. You just have to soak the labels off. If you have a couple wineries around you, find the one that has the labels that come off easy. I’ve clean off more than a couple hundred bottles. Good luck.
Bottle related so not a total hijack. I've been looking for amber because they are supposedly superior for long term storage. Why aren't they more popular? I know beer vendors, where light skunks beer, sell in green because of sales.
