I think we're a few bucks more than that, maybe $23-29 depending on sheen. I don't think I've ever used their semi. I love that paint tho. Covers great. Sometimes I feel silly buying anything else for walls, I mean it works so good. I have a big job coming up using that on lids and Regal Select matte on walls. Mostly just sold the regal cuz the owner seemed to want to pay more so that he thought he was getting the good stuff. I don't mind, but I'd put ultra spec in my house all day long. Truth be told tho I'm getting ready to do some painting around our house, kitchen, bath that kinda stuff, and I'll probably use aura. Oh well, there goes my theory. It's good paint tho.
The wife wants me to repaint our kitchen cabinets. Last time used aura satin, in a nice green, I think it was 508. That was probably 5-6 years ago. They held up pretty good considering we had lots of messy teenagers etc. got worn around the inobs in some places. Now she wants white so I may try the Ppg breakthrough on them. Gonna see if the extender helps it flow.
