I try to keep my eye out for sales, and take advantage of them when they occur. I seem to go through co-wash the fastest, but at 79 a bottle on sale, buying a couple of bottles ahead seems like a cheap indulgence. I also try to get larger sizes of the things I know are HG products for me. Other than that, I'm trying not to buy ahead significantly, unless something I love is being discontinued.
