I have been participating in the skymiles dining program by Idine for about a year now and love how easy it is to get those miles. However, I was curious how they can afford to buy all those miles for people??
I did notice they have a max of $600 at most restaurants and was just curious if those costs are split between them and the restaurant or what??

Anyone have a clue about how this all works???

I know I shouldn't care, just as long as I get the miles, but I am procrastinating reading for class tomorrow and just got some dinner, so it sparked my curiosity...
