$20 for Roundtrip Ticket to Las Vegas, Oakland, San Francisco, or San Jose from  BoltBus ($60 Value).  These BoltBus deals always sell extremely well – you get so much for your $20!  Limit five vouchers per person; you have 60 days to use from date of purchase.  Fantastic idea if you’re planning a Los Angeles visit – you can visit a couple of other CA cities on the cheap or throw the dice in Las Vegas.

Buses shuttle passengers between West Coast cities in comfort enhanced by new leather seats and seatbelts, WiFi, extra legroom and electrical outlets. 

More money, but another option:
