Check Skymilesshopping.com too. I was buying a BBQ grill but rather than walking into the Home Depot and spending my $300 (1 mile per dollar on my Plat Skymiles AMEX) I bought a gift card from homedepot.com via skymilesshopping.com and got 3 miles/dollar + my 1 mile/dollar on my card. Very quickly I got 1200 skymiles for spending what I had planned to spend anyway.
