I got this error
"Google reCaptcha verification failed."
Probably your browser. Can you try it on a different browser?
I had this problem. Fix it like this...
1.) Go to their website (
https://www.bucksbullsbears.com/) and signup for their newsletter first at bottom of page. There should be a "re-captcha" that shows up when you do this.
2.) Keep that browser window open. Go to the signup link:
https://www.bucksbullsbears.com/giveaways/v3/?lucky=424353.) Since re-captcha already verified "something" it now works for this page.
Caveat:
1.) This is a theory but it worked. It's just programming theory worked through. Maybe not even the answer, but again it worked. It might have loaded "after a while" but I forced it possibly like this.
