Did you know that if you join their email list, they will email you Boston Pizza coupons, including totally free food!?
Initially, they will send you a coupon for a free starter with your meal.
On my recent 1 year anniversary of joining the email newsletter, I received a printable coupon for a free 2 topping individual pizza. The coupon was valid for a week from the date of receipt. But sadly, I cannot share the offer with you as it is a unique email - you'll have to sign up to receive these kind of offers yourself!
On my birthday, they emailed a coupon for a free gourmet pizza or dessert. And there was also an email on Valentine's Day, so they really don't contact you very much.
Remember, if you're going to be signing up to the mailing lists of companies so you can get deals in newsletters, I recommend setting up a new disposable email address, which you can use just for this purpose. For example, I use a spare gmail address where all the junk (and deals) go to!
