I have $400 worth of United vouchers + 2 x 10% off which could be worth a lot if properly used:
2 x 100 Electronic Certificates exp july 10, 2013
2 x 100 Paper Certificates exp june 8, 2013
*2 x 10% off electronic certificates exp june 8, 2013

*Terms for 10% offer are: 10% Off E-Certificate: For travel to and from any city served by United or United Express during the travel period specified. Save off published United Economy fares on a qualifying flight purchased at united.com or on a united.com worldwide site. Ticketing and travel by June 8, 2013.

Selling for $415 or best offer, PM if interested.

To clarify some questions I received:

From what I can tell:

• The 10% off will work only if there is only one passenger on the reservation
• You can combine the 10% off with one of the $100 off travel certificates
• You cannot combine the two 10% on one reservation.
• You cannot use more than one of the $100 off travel certificates on one reservation
• The 10% off appears to only reduce the economy base amount, the taxes and fees will still apply at the original rate (I'm not 100% about this)
• If you want to book for more than one person, its best to split the reservation and apply one 10% and one $100 off on each reservation
• These should all work from anywhere, so long as its an actual United flight (not some other * alliance or partner flight)

If anyone has more experience with these, feel free to correct me on anything I said above.
