Had to book transportation to/from Long Beach Airport and found a good deal with Super Shuttle.
Save 15% with Visa card for Round-trip transportation: LE74Z
Save 10%: 4B65C (better for one-way or single passenger)
Or depending on your travel you can save a flat $3: UYR59
Then you call: 800-726-9807 and they will email you a $10 rebate for your booking that you can redeem for cash. (Sure you have to listen to a short schpeal about something but the phone call took me no more than 45 seconds to deny the $1 sign-up)
I got a one-way transport from LGB to Disneyland for 2 people for $29.60. Not a bad deal.
Have you got your $10 from calling 800-726-9807?
