200kg of beans and rice

Hi. I'm an American living in the Netherlands. I'm part of a group that encourages storing 1 year of food for the whole family. Where can I buy a year's worth of dry beans and rice in the Netherlands? My neighbors are telling me to buy at the local Asian food store. Is there a better place to buy food in bulk in the Netherlands? Also, where can I buy mylar bags and large air-tight plastic buckets to store the food? Thanks. Justin
