When all else fails... try Amazon.com. They have everything.> All this praise for the yellow can and I can't find it anywhere! Grrr
I know what you mean. First I went to Walgreens and it seemed like they had everything but the Yellow. Then CVS and it was just Red and Green. Then Target and they just had tons and tons of Green and nothing else. Finally got lucky and found a Yellow can browsing my local grocery store chain. It's odd that this can gets so much praise here but it's the one stores choose to carry the least of.
I've used the Green and Yellow now. Compared to shaving soap they lack slickness but they are okay. They have a very nice thickness and density to them. The smell, though faint, really does grow on you. I like Green to the point where I would love to find a shaving soap with the same scent, but more power to it.
One other difference between Green and Yellow for those who care about such things. Green seems to have a much longer ingredients list including Parabens where Yellows lacks those.
