American: Earn 2,000 Bonus AAdvantage Miles and save up to 25% when you purchase AAdvantage miles

Every month it seems like American AAdvantage is releasing a different buy miles offer. This time it is a small bonus but the miles come at a discounted price. If you purchase the maximum amount of 60,000 Miles you will end up paying 2.06 cents pre tax (2.2 incl tax) per mile which isn't too bad for an AAdvantage mile purchase but when you consider you can buy US Airways Dividend Miles for around 1.75 cents and likely be able to convert those to AAdvantage in the near future it doesn't look that good.
