I need to set up multiple locations on my business facebook page

I have recently set up our companies Facebook page - Hamseys, a bed, mattress and furniture company in the south east (links below). However as we have multiple locations of stores, I want to be able to show all of our stores on the maps on our facebook page rather than just one. However Facebook makes this difficult! Can someone help me do this please?

I know it is doable as I can see it on Topman's page, I just need someone to do it for me! - We only have 7 stores though so won't take long!

Many thanks and I look forward to hearing from you!
