What a DEAL!

From time to time Kris and I allow our favorite mechanic to change the oil in our cars. Other times we just go by Valvoline or Jiffy Lube. Granted, it is cheaper to do it ourselves...but well, it takes time and is annoying. So we choose to pay for it. The air filter on the other hand, most of the time we just pick that up from Walmart and change it ourselves. $10 or so and it's done. So it makes sense that in an effort to gain new business, a company would offer a free oil filter with the purchase of an oil change. But this?

FREE OIL CHANGE WITH YOUR OIL FILTER???? Is it just me or is that a really GOOD deal??? We didn't need an oil change OR a filter, but it was quite tempting! Also, is it done out of the trailer?
