For awhile I was paying my approx $2K/mo mortgage via Evolve using $500 VGC's, then the rules changed and I reverted to my old way of paying my mortgage via automatic withdrawals from my checking acct. Although it should have been incredibly obvious to me all along, I only recently caught on to the fact that it's almost as advantageous to pay the mortgage via MO's (especially if you still have a 5% cashback card).
