My experience with them is very slow shipping when I ordered my mudflaps from them 2 years ago.
..and then about 4 months back I had a charge on my credit card from CarID for a Tonneau Cover for a 2015 F150 for $967.39 and I hadn't even visited their site, let alone was looking to buy one for a 2015. That was a fiasco but luckily my credit card company has great customer service.
I apologize for the late reply, just configured my notification setups. We do offer coupon codes on most of our products! Check current promos and sales on this page: https://www.carid.com/coupon-codes.html
