I am a US visitor on a 3-month stay in Amsterdam.
This is the easiest and most convenient place for groceries. Its relatively cheap and it certainly helps that you can find one every few blocks. However, many of the Albert Heijn branded house products are of cheaper quality (such as dishwasher pellets and other detergents) and less effective.
Their bakery offers some delicious treats and fresh bread that i eat for breakfast. Visiting the Netherlands i know that if i ever need something I can quickly find this place.
