Hi all, I'm kinda new to LV, but would like to buy my first one. What is the difference between buying at online site (eBay) vs. LV Store. I know that I should be carefull about authenticity if buying from eBay. But what about LV previledges, like will you be able to take your bag to LV store to get any repair if there's any damage down the road? I heard that if you buy in LV store they put your data in their system? Is this true? please advise me! Thanks so much!!
