Cutting out the Middlemen/Purchasing straight from factory

Is there a guide on purchasing straight from factory? I was just quoted on 1 bag a simple “Louis Vuitton On The Go MM” and the seller wanted almost $500 for the bag plus almost another $100 for shipping, which to me is insane for a rep. In a couple years these middle men will be just as expensive as the actual authentic flagship stores which defeats the purpose of why we are all here. If anyone knows how to go buy straight from factory please let me know!
