I ordered the HuskyLiners 98891 Floor Liners for my 2012 Hyundai Elantra on 5/29, received them 5/31. Order #15417. Apparently they have warehouses all over the country to ensure quick delivery.  They had the best price on the net. Item arrived in perfect condition.

Their website needs a little work because I found the item thru Google and not directly from their website.  You also can't edit your cart unless you register first which was annoying.  Items could use product descriptions - you have to get info from the manufacturer's site.  The real-time inventory was a plus.

Deducted a star because their website needs work.

Bought some wire looms for my Chevy from them. Great price, service, and shipping speed!
