Often CVS has three day sales good for the first three days of the week. They are often for free after extra buck items and other super sale prices. There are a couple of things to remember about these sales. They will not start early with the rest of the ad on Saturday nights. Other extra buck deals will
print out fine Saturday nights at a CVS that generates the ads early (which is almost all) but these will not. Also, many stores will not give rain checks for these items. My store always has, but I have read many shoppers have been refused. I have emailed CVS customer service to ask about this and will post when I receive an answer. So keep your eyes on the ad and be sure to note if the sale is for a limited time.
