It was good

Service was great! Fast de!livery!

I ordered these tires for my sons truck and then received an email stating that they couldn't fulfill the order. I then emailed them with my concern and they apologized and more or less said they would check it out. Before anyone got back with me about my refund I received an emailed that the tires were being delivered. Then the delivery truck was in my driveway with my purchase a day earlier than I was originally expected. I was very excited because the tires were a Christmas gift. Santa pulled this one off!! Thanks to Autoplicity.com we will be using this website again!!

I got my tires way cheaper ordering off the website. They were exactly what I ordered. The right size I ordered. And delivery was WAY faster than expected!

Website was fairly intuitive. Would be nice to have a search feature.

Easy!!
