I stopped by my client's store today to pick up some groceries. While there, I didn't bring anything up about the project other than when I was checking out, I asked if he was getting the weekly emails.
He said he got this week's (although I have no idea why he didn't get any other week unless it was spam filters).
He offered without any prompting from me that he was now ready to start promoting and would have flyers up in the store today.
We'll see what happens.
