So so far I've tried a bomb, a bubble bar, and last week I tried a bath melt. My flavor of choice was MMM Melting Marshmallow Moment ($7.95 CAD). It smelled lovely, turned my water opaque, but did not froth (and supposedly it's supposed to). It did not matter I still enjoyed it. I have the best sleep after a good long Lush soak... only regret is not trying it sooner :)
I think once I've sampled all that I want individualy, I'll start to mix and match the products, like a bubble bar with a bomb.
I've also picked up a vegan conditioner... haven't used it yet, hope it delivers.
