VSP,,how are you making any money??

We have been taking VSP for about 3 years.. We have been looking at some of our reimbursements and on a pair of SV glasses we are only getting a payback of 90$,, and then we have the frame fee that we paid,, so sometimes we are only netting 30$$$ WTH.. on progressives we make more,, but we are losing our shirts on SV jobs.. Am I missing something here? Do I need to really up the price of the frames??
