Is this a closeout part? I've had issues with items a couple times and they made it right-- once a set of spark plugs where the boxes were all tore up and the crush washers fell out (I found some in the bottom of the shipping carton but could not locate all of them). They refunded me for every spark plug and told me to keep them.
Couple oil filters I ordered were not the size advertised-- full refund, keep the oil filters. I think this is par for the course for their low-cost closeout stuff.
The only really problem I've ever had is when I cut open an oil filter that was listed as fitting my 07 Pacifica, only to find out that the filter did not have a bypass valve inside! So clearly this was a misapplication, an error in their catalog. I contacted them and they refused to update their catalog and basically told me to pound sand. After that experience I avoid shopping with them unless I'm saving a substantial amount of money.
