I know this is still working because I just requested mine, but if you hurry on over HERE and submit a Butterfinger replacement bar claim form it sounds like you will get a coupon for a free Butterfinger.
This is for the first 100,000 only! I have a feeling we are going to see a lot of interesting freebies and coupons today!
Worked for me, was giving me problems with email address but worked fine once I typed email address in all lowercase.
This is already gone. 🙁
