I typically always have a great experience here- hence the stars. On this occasion, I was told that they were out of my type of oil and had to upgrade me. I said sure, as long as it's the same price. Sure enough, they ended up charging me full price. I don't understand why the consumer should have to bear the brunt of a inventory error. In the scheme of things, it wasn't that much of a difference in cost, as I initially did not notice. It's about the principal. I felt a little taken advantage of. I'll stick to AAA's oil change.
