Order was placed for a particular part (LH) and a (RH) part was shipped. Rock Auto would not correct their error. There is no "readily available" customer service number that can be used to discuss a problem, only an on-line process which summarily determines your fate. The part in issue cost less than the "jacked up" shipping costs so I was beat out of less than $20 total. Lesson learned; I would not purchase from them on-line again, especially anything of significant value. Instead I would use one of the national brand stores' on-line service and pick the parts up locally.
