United Airlines is offering a targeted up to 25% off miles purchase offer. I received the email today, and you have to access the offer through their email link. I tried to access it directly through my United miles account, and it was a no-go. "Purchase award miles now and save up to 25%. Buy MileagePlus® award miles for less and start planning your next getaway. For a limited time, save up to 25% on miles you can use toward award travel to more than 1,300 destinations with United® or Star Alliance™ member airlines. Hurry, this offer expires at 11:59 p.m. CT on January 10, 2014." Of course, you have to decide for yourself if you really need the United miles. Even at the discounted rate, these miles still end up costing ~2.8 cpm, if my math is correct. Comments welcome.
