I received an e-mail from United about an interesting event coming up that United MileagePlus Mastercard holders could attend and pay for by using a small amount of miles.For 2,500 miles, United is offering the chance to reserve a spot at a private fashion show featuring men's and women's apparel at the The Mall at Short Hills in New Jersey. The event takes place inside Neiman Marcus on April 3.No, I wasn't interested but I have to say the offer sounded pretty fair and might be of interest to some of you. Please keep in mind once again that this offer is only open to United MileagePlus Mastercard members.In addition to the fashion show, the event includes drinks, hors d'oeuvres and a $50 Neiman Marcus gift card. This sounds like a pretty fair value if you are into fashion. The $50 gift card alone makes this offer a decent one.You can reserve up to four tickets to the show. To save a spot, send an e-mail with your name, guest's names, the last 4 digits of your MileagePlus account and your address & phone number to email@example.com. You will be contacted within a few days by phone or e-mail to complete your reservation.
