Prices can vary wildly. Even shipping rates can be all over the place. One place wanted $600 to ship the skid plates to me. The place I ordered from charged $30.
Best thing to do is Google the specific part number and a ton of sites and prices will pop up. Find the lowest and work from there.
X2 on google with the part number and don't forget to check the local dealer's parts counter. I have found many items that are the same price as the online price and I didn't have to wait for it to arrive.
