We are three weeks away from Thanksgiving. There is no rush. The offers will come. They are to begin 11/4. Let's not panic until at least 11/4. It won't be a secret. We will either be notified, or I am sure ibotta will clobber us all over the head promoting this. So just relax for a few days.
IIRC, I believe I read that you may have to get all Turkey offers via the Chrome extension.
I also think it was only with WM.
So, it may not be something you can do thru the 'regular' way of just adding to your mobile and going to the store.
Again, all the details will be apparent once ibotta rolls out all the details likely later 11/3 or early 11/4.
