#1 Online flea market
Were you planning on selling old toys with the kids at a flea market on King's Day this year? You still can, just online! On King's Day, take some pictures of old toys and put them on an online auction platform, such as Marktplaats. The rest of the holiday, you can keep an eye on your sales together. And... you're probably not the only one doing this. Go on an online hunt for the best bargains.
