I personally LOVE the feeling of walking into the LV store and buying a bag I ask the SA to bring out some other bags for me to look at.. I can feel all my future purchases, look, smell and just enjoy all those LV items in one store. But if the sales tax is really high in your state it could definitely be worth it!!
If you read their policies, that's not entirely true. eLuxury charges sales tax if you live in either California or Tennessee. (They probably have warehouses in those states.) So if you live anywhere else, you're golden. In my case, I paid $18 tax AND $16.50 for shipping on a pair of Rock & Republics. Good luck!
I live in Illinois (yeah, no sales tax) and the closest store to me is about 1.5 hour away, which is not too bad. The sales tax there is about 6.6 percent; that's alot when I'm spending anything over $500.
Personally, I feel uncomfortable when going to the LV store. The service is terrible when I don't dress "wealthy". I tend to get ignored and when I enter the store and SA acts like I'm beneath them. So I prefer to purchase my stuff online like Ebay and soon Eluxury (don't have to deal with them).
