Please help, I need to remove sidebar in woocommerce

Hi everyone,

I am a total noob and I am not techie at all but really could do with some help please 🙂

My site http://mattwebservices.com has woocommerce plugin installed and i have made it really nice but I cannot seem to remove the sidebar from the shop? when you are viewing the shop http://mattwebservices.com/shop all seems good until you scroll down and see the sidebar, I dont want to remove it in any other pages just the shop,

I really cant seem to do it 🙁 I am struggling, I would really appreciate your time!

Kind Regards
Matthew
