I am off to Bermuda on Friday (August 17th) and would like to visit the Louis Vuitton boutique. Are the prices any different there (think I've read posts that state it's cheaper)? Or is the only difference sales tax? I'm in MA now, and we have a tax free day on Sunday (August 12th); should I just buy a bag here in Boston (tax-free) or wait for Bermuda? Thanks in advance for your advice/opinions.
