CVS often sends emails to customers with coupons to use in the store. Some people, myself included, have reported signing up for the emails and never receiving any. Others have gotten them for a time, and then not. How they decide I do not know--I know people who shop a lot and get them and some that shop little and do and the same is true for those who do not. Well here is a link to sign up for emails and you will receive a CVS $4/20 coupon within 24 hours of signing up. I had no trouble signing up but I have read some reports that some people try and it says they are already registered to receive emails. So who knows. I did this several weeks ago and have received one email since the $4/20. But for those of you who do not get the CVS emails it is worth a try.
