Sherwin Williams Emerald Paint 30% off $54

I have been looking for SW paints for few months. They used to have it regularly. But recently I haven’t seen any offers on paints. I saw an email from them today mentioning 30% of Emarald paints. I need paint for trims. This might not work for me but hopefully somebody else can use this.
