United Offering Big Bonus on Purchased Miles

United has a pretty compelling offer goingon the sale of MileagePlus miles.  The offer is setup as a mystery bonus so not sure what other people have received.  Both Emily and I received the 75% bonus offer.  Here are the details:

• Buy miles through 4/20/17 to receive the 75% bonus
• You can buy anywhere from 1,000 to 85,000 miles
• 5,000 - 14,000 - 25% bonus
• 15,000 - 29,000 - 50% bonus
• 30,000 - 85,000 - 75% bonus

If you received the 75% bonus offer, you should consider buying no less than 30,000 miles.  If you didn't, you probably don't want to take advantage of this offer.

If you opt to purchase 30,000 miles, you'll get a 22,500 mile bonus and the entire thing will cost $1,128.75 with taxes.  That breaks down to 2.16 cents.  I'm not a speculative buyer at that price but this offer could be worth it in certain situations.  A one-way business class ticket to Europe (on United metal) will set you back 57,500 miles.  You can outright purchase those miles through this offer for $1,241.  That's way cheaper than buying the ticket although you'd be foregoing award miles and miles towards elite status qualification.
