i bought my azur speedy from Neiman Marcus in newport beach, ca last week, and i love it! i noticed however, that i didn't get any little booklets or papers that prove authenticity... are they important (like say, if i ever want to sell it in the future) and should i go back to ask for them? i also didn't get my bag in a box... just in the brown LV shoppiong bag. is the NM LV not doing its job? or does it differ from LV store to LV store?
