Great customer service, very rare to see such happy, accommodating employees. I even heard one employee on the phone helping a panicked driver figure out a tow company to call (not a service discount tire offers).
Went in for a nail in a tire that the dealership found while doing an oil change (they don't do tire patches). Couldn't remember which tire the dealership said it was and Discount let me know it wasn't the one I told them and checked the others.
Busy place, I would aim to come in during the week rather than a weekend. And make an appointment online ahead of time to further minimize the wait.
