I just made a great discovery I wanted to share with you all. www.radioshack.com sells all the Caig DeoxIt, ProGold, etc products from their web page only. Just bought DeoxIt liquid, 7.4m with appl brush for for $7.49, $2.50 shipping. The 11 oz. spray is $11.95.
Whatever your opinion is of the product, The Shack seem to have the best prices on the Caig product line. Here's the link: http://www.radioshack.com/category.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F005%5F012%5F000%5F000&Page=1
I believe that Parts Express (www.partsexpress.com) also carries Caig and their prices are very good. In any case, a little goes a long way with their products, so price shouldn't be much of a consideration.
