Smashbox Photo Finish Foundation Primer Light Review

Smashbox Photo Finish Primer, in any formula, is the best!  I love it so much but use it so sparringly.  It makes my face feel so smooth that sometimes I just put that on and just say to myself "what the heck, I'll go au'natural with just my primer."  My makeup never runs, or bleeds when I am wearing Smashbox's primer and at the end of the day when I wash my face it feels so smooth, almost as if it was never dirty in the first place!  I will always bounce around and try different foundations, but the primer that goes underneath (95% of the time) will always be the same!  The only vice I have is 1.) the bigger bottle runs $36.00 and it seems like I can never get every last drop out.  I feel like I am wasting so much even though I try so hard to get ever last drop.  2.) the price, yikes, if I felt like I was getting every drop I wouldn't mind the $36.00 because it would take me at least 2 months to use it all (I use sparingly too) but I get the travel size which is half the size and half the cost where I'm not loosing anything in the value, but I'm getting every-last-drop!
