I saw some for sale on EBay a while back, so I guess you can if you hunt around the internet. Try googling it and see what comes up. Not sure if any shops sell it, but some where must do. They do work well for a long time don't they.
Yes, look in amazon or ebay. Ive seen some in target, they arent that pricy and most important they do their work so well, of course it hurts a little but you get used to it.
