I just called and they said the info was entered into their system on March 26th and that it's typically a 8-10 week wait after that point. That puts it at between May 21st and June 4rth 2008. That's not too bad I guess. I hate the waiting though.
When I was a teenager I won a T-Shirt playing an arcade game called
Stun Runner. At the end an address and code was given to send for the free mail in. I had pretty much forgotten that I even mailed in the offer when 10 months later it arrived in the mail.
My previous history with mail in rebates and offers in general lead me to not go for a product over another because it has an offer unless it's a really really good one.
