I put $60-100. When I buy I usually am stocking up so will buy liters of stuff or some B&A gel which is a little pricey. The same goes when I buy from Jessicurl, I usually stock up by buying liters.
2b/3a, primarily use Jessicurl and DevaCurl products, Curls Hair Tea conditioner and various gels. I'm modified CG-ish since 5/04.
