I use Bare Minerals and the large foundation lasts me at least 3 months, longer in the summer because I wear less make-up. Are you sure you're applying it correctly? Even the smaller size that comes with the starter kits should last close to a couple of months. You said the mineral veil didn't come out at all? Sounds like maybe it all got damp somehow, I'm not sure, but I have never had any problems like what you're describing, and I've been using Bare Minerals for years. And yes, I wear it to bed all the time, I don't ever wash it off at night (but I don't have white pilowcases either!). Do you have a store near you that sells Bare Minerals? Target is selling it now. I would try buying it that way, and if there is a problem it could be easily returned.
