H.E.B. P&G Roundup ... get $10 Coupon with $30 Purchase

Yesterday I visited my local H.E.B. for a special P&G Roundup deal they have a few times a year. 

I took advantage of this deal by purchasing 4 bottles of Tide @ $7.54 each for total of $30.16 ($30 minimum).  I used 4 of the $2.00 off yellow "M" coupons to bring that total down to $22.16.  I bought a few other items as well; so my total out of pocket was a bit more.

After checkout I was rewarded with my $10 catalina. 

Now that may not be the best deal on laundry soap; but I've developed quite a fondness for Tide.  So for me it is a really good deal.

The $10 catalina can be used between May 15 - 28 on purchases of $30 or more.  I'm a little concerned about it being a "B" coupon; because H.E.B. has changed their coupon policy by not allowing the stacking of coupons.  I will more than likely apply that coupon for items like meat and produce.
