Just returned from getting an oil change and was pleased with my experience. They didn't try to upsell me or add any extra services. The prices are definitely reasonble and they finished in an hour, which is how long they estimated it would take. It was $28 for a premium oil change, which my car requires, but only $16 if you use the standard Shell oil and bring in a coupon (they aren't hard to find).
I can't speak for any of the other services, but if all you need is an oil change I'd say you can't go wrong.
