Looking for my Mineral Hygenics gals...

I need to order refills for the two different foundation shades and the translucent base/finishing powder and I'm trying to figure out price versus product size. Has anyone ordered the foundation for $25 NOT in the starter kit? Is it bigger than the starter kit's foundation size? I'm trying to figure out what makes sense...for $60, I can order another starter kit, but I don't need more brushes and I have plenty of bronzing powder, but if the foundation containers are the same size, it's a better value to just reorder the starter kit (would save $5-10 and get more). BUT...if the $25 foundations are larger than what they give you in the starter kit, then I'm happy to spend extra to have it last longer.

Hope that makes sense, LOL!
