How Does a Buy One Get 50% Off CVS Sale Work?

Which items will be reduced to 50% at CVS when you are purchasing items of different values in a B1G1 50% off sale?  This question has come up a lot this week as we prepare for the Covergirl sale and the use of the $8/2 CG coupons and the Spend $30 get $10 gift card deal.  I have rarely bought any of these deals, and when I did I would just check out two at a time to be sure I got the best deals--but that is not always convenient.  So I asked around to find the answer for us all. Here is what I know:

• Two items of the same price:  obviously one will ring up at half.
• Four or more items--purchased in pairs of the same price (example:  2 @ $3, 2 @ $4, 2 @ $6):  the second price of each pair of like prices will be reduced to 50% (from example:  one @ $1.50, 1 @ $2, 1 @ $3).
• Two items different prices:  lower priced item reduced to 50%.
• Four or more items all of different prices:  no one knew for sure, but more than one person thought the lowest priced items would be reduced to 50% off.

If you have an experience with these types of sales at CVS we would love for you to leave a comment and let us know.
