My son lives about 1500 miles from me.  He had asked me to get him an Industries SuperFlow Hi-Volume Air Compressor for Christmas.  
With a couple of click on my computer, the compressor was ordered to be shipped to him and was paid for.  He had the exact compressor he requested within five days.(and that included the weekend)
One word sums up my experience---EASY

Very quick service and lowest price.
