I was in the local Sherwin-Williams getting some samples and while talking to the paint rep found out that they are going to have their (what appears to be every other month) 40% off paint & stains deal. Also painting supplies are 30% off. As usual you can stack with a few different coupons to sweeten the deal even further.
The deal starts Fri 9/21 and runs through Mon 9/24
$10 off $50 coupon – multiple uses per barcode : https://www.sherwin-williams.com/…tail-pages
$15 off $75 coupon – unique code thus one use per print – https://www.potterybarn
If you’re an Amex card holder you can stack that on with the $25 back on a $100 purchase offer. See for more details
