On my search for more online stores I found a charming website where they sell the real deal, really old-styled furniture, lamps and accessories: designlover.nl. It’s for those who wish to visit flea markets but can’t care less because of all the hassle. If you’re lucky enough to find what you’re looking for you will need to carry it with you until you head home.
So if you’re not a fan of that much physical action there’s always the people who do the collecting for you. Do bear in mind that you will be paying a little more for the effort.
