I've been using this car wash since it opened. It does an ok job washing but i go for the self serve vacuum. On 4/12/13 When I was purchasing my wash it gave the option to pay for one in advance. I went for it and I'm sorry I did. It unfortunately expired on 5/13/13. On 5/17/13 I went to super Star to see if I could still use it since it was only 4 days expired...and it was something I PAID for in advance. Of course they would NOT honor it. It is my fault for passing the expiration date but any business with half decent customer service would honor it.
