This is a perfect place for you to buy gifts for kids. This shop has everything you can find for a kid. I have found many cheap post cards for 1 Swedish crone each. That is very cheap price and a perfect thing to buy when you visit Tumba and then send to your friends.
This centrum have some shops, a food market, cafe´s and the most important Systembolaget, where you can buy alcohol. Weekdays all the hops are open between 10.00 and 19.00. On the weekend there other opening times and Systembolaget is of course closed on Sunday too.
