Today is the last day to get $10 off each painting supplies purchase of $50 at Lowes. This includes paint and any supplies you need to get the job done like caulk, tape, buckets, paintbrushes, etc. The wording says $10 off EVERY $50 you spend, so you would get $20 off $100 and so on. If you’ve got any coupons from moving packets at the post office, stack them to save another 10%.
