Hi Debbie,
I don't have Neuropathy, but I take Vit B12.
I buy it from iHerb because I'm in same situation and can't get it here in Australia.
Just check the prices as they vary from week to week.

I've been buying the Natural Factors, B12, Methylcobalamin, High Potency, 5000 mcg, 60 Chewable Tablets for some time as it's about $5 au cheaper than the Jarrows usually. It depends. [I buy Jarrows in other things, Inositol for example. It seems to be a good brand. I just try to change around because of the costs involved]

There are a number of brands in the same potency, but some seem too inexpensive and unknown brands to me and others are way too expensive.

Seeing I'm paying for postage, I usually try to get more than one item at a time.
