New to CVS couponing. Stacking threshold CRTs?

Hey guys! I started CVS couponing a few weeks ago, but have only done a few simple transactions with one or two products and usually just 1 CRT/1 MFR coupon. I’m trying to plan a slightly larger haul using a bunch of different CRTs and just wanted to double check that everything will stack the way I think it will.

If I have a $6 off $30 purchase CRT as well as a $3 off $15 oral care and a $3 off $18 hair care, will all $12 come off a $30 purchase, provided I’ve met each individual threshold?

I know if you try to stack the same type of threshold CRT (ex. $2 off $10 oral care and $5 off $15 oral care) then you need the combined total of both thresholds for both CRTs to apply, but since the ones I plan to use are all different threshold CRTs, I wasn’t sure.
