Sidewalk vendors are open Mon-Sat from 9 am ish to 5 or 6 pm ish. There are brown huts where they lock up at night. Most closed Sunday as are most stores except some jewlery places. Might find one available???--best then to go to the fleamarket. Don't know of vendor websites or phone numbers in aruba but you could try calling for some help on questions to 1-800-TO-ARUBA Mon-Fri around 8:30 to 4 PM. Also, try
www.arubavibes.com They sell on line and have a store downtown. I'm not sure that's correct. if not, I'll repost it.
