Post/ Post offices
The easiest way to get stamps is to buy them from the place you buy your postcards. A stamp for a letter or postcard within the Netherlands is € 0.44, within Europe it is € 0.77 and the rest of the world is € 0.95. Otherwise just go to a Post Office like on the Weena 296-298 (open Mon-Thu 9am-6.30pm, Fri 9am-9pm, Sat 10am-5pm). Drop your mail in any red/orange letterbox. There are two slits: on the right for Rotterdam and local zip codes and on the left for the rest: 'overige postcodes'.
