Update: According to some readers, the email only mentions the $16 cashback. At this point it is safe to assume you will only receive $16 when making a booking.
Ebates is continuing to offer great cashback deals in celebration of their 16th birthday. Today they are offering $16 cashback on Virgin America flights plus a $16 per booking rebate. The terms on their site seem to be very vague, but this information went out in an email to subscribers.
I didn’t receive the email, but according to guv1976 on Flyertalk, the email said this: “Virgin America: $16 Cash Back Today Only + $16 Per Booking Rebate”.
If you don’t already have an Ebates account, you can find a signup link and many other cool things here.
