You can half them or even quarter them! Same with most of their other products!!! So they really last a while! To break a bath bomb i take an ice pick and then a hammer and smack it right along the mid section, then if i want to break it again into 4's i take a butter knife and slice it So you can really get quite a few baths out of one bath bomb!
as far as the bath melts go- a little can go a long way- i've broken mine up into halves and 4's depending on the one i'm using. Same for the bubble bars- one Bathos bubble bar i cut into 6 pieces and got six baths filled with bubbles out if it! There's a huge forum on the Lush website devoted to the products/ how to make them last/etc.
That is good to know.. I will have to order them from the website since the nearest store is about 2 hours away and I will NOT drive in Los Angeles. I hate driving here! I need to save my money. I want the lavender products that help you sleep. I used up all my lavender bubblebath I got at the 99 cent store and they didn't have any when I was there last Saturday.
