We were told (and saw for ourselves) that electronics including digital cameras were no cheaper in St. Thomas or St. Martin. The real shopping attraction is the jewelry.You're best price will probably be the internet best price on the camera but let us know how you do.
Was there in October and bought a new 35mm (to replace a 6 year old one) (already have a digital). Best stores to check out are Royal
Caribbean and/or Boolchands (sp) ... comparison shop between them and bargain with both. Do check your prices at home first. My camera was $55 less than at home.
