US Airways has a new promotion for buying Dividend Miles this March. You need to log into your account to find out your bonus amount that can be 25%, 50%, 75%, or 100%. This purchase offer is valid until March 31, 2013. You can log into to the Buy Miles page and find out your offer here.
The price of a mile under the 100% bonus offer is 1.9 cents. I would definitely NOT consider buying unless I would have been targeted for this highest offer.
You can read my take, when and under what circumstances it can make sense to purchase airline miles here.
US Airways has monthly Dividend Miles sales. This can be from an OK to a bad offer depending what version applies for your account.
