I need a couple hundred skymiles to have enough for an award ticket I'd like to book very soon since if I wait longer, I'll have to pay an additional fee for booking less than 3 weeks to departure. Any ideas on how to cheaply get a couple hundred skymiles posted quickly? I have a delta amex but that'll take too long to post and I don't want to purchase thousands of miles when I only need a couple hundred literally. Thanks for any help.
