Just got an e-mail from BizBuyer:
"To receive your movie tickets, just log on to your BizBuyer Account at http://www.bizbuyer.com and click on "Modify Registration." Once you fill out your registration information, we'll mail you two free Movie Cash(tm) certificates. Act now - offer good until September 8th."
If you're not a member, hopefully you can create an account and get in on the offer.
Oops - found the small print:
"Registration information must be updated by 11:59:00 pm PDT, September 8, 2000. Offer valid for members registered before June 7, 2000 only. "
