Hands up anyone who actually sees the promotional email from sites they register with? Once you've got the freebee they used as bait, why clog up your life with more meaningless spam.
Given that disposable email addresses are so common, if not yet ubiquitous, how about the same thing for mobiles. Most of the telcos will send you free SIMs in the desperate hope that you'll forego your existing provider and sign up with them. Just slip one of these into your mobi at the airport. Give the number to the nice person behind the check-in desk (or when you booked online), take your discount, and toss the SIM in the bin just before you board.
Just remember which SIM is your primary - the security people have a dim view of bin diving at airports.
