Both the $3.99 and $4.99 sizes of Pantene trigger the $5 gift cards, so go for the cheapie if available. I love the Quattro razors at $5.39 since the $7 coupons make them so cheap! Obviously I got more than the items shown, but all are working as they should. I’m running them all in one transaction ’cause it’s easier. Here’s a screenshot from my first transaction using the $4.99 Pantene (with a couple of additional items tossed in – think they were slightly over $4 in total). After coupons my REDcard subtotal was $67.18 less $35 in gift cards. Using the cheaper Pantene would bring it down considerably.
