Did CVS change how ECBs are rewarded when using coupons?

I just went in store and wanted to do $10 ECBs after $30 spend. I bought 2x oral b floss 2 packs ($10.29 ea), and a 84oz tide for $12.99. 12.99 + 10.29 + 10.29 = $33.57 spend (after sales before coupons/deals). I had a $3 off tide, B1G1 50% off the floss, and a $2 off 2 for the floss. Total came to $25.41 after tax. No ECBs rewarded. Pardon me as I've taken a step back from couponing for about a year, but I always thought the ECBs were awarded based on pre coupon total. Did this change?
