Through the comments in the CVS Match ups post and emails from you guys, we have determined that the Crest ECB deal at CVS this week is a limit of 10, not 2. However, it does appear that you can only do 2 deal in a transaction. Here is the original deal:
Crest Pro-Health Clinical Gum Protection $3.49
Get $2.50 ECB (limit 2 per transaction/10 total or 5 transactions of 2)
use $1/1 from the 8/1 PG insert
as low as FREE each after ECB
(Thanks to everyone for the comments & emails!)
