The Green Place is my favourite shop. Check it out. They have three strains for €7/gram (White Widow, AK47, Jack Herer) and some stronger stuff for more... try the Amnesia 666 for €9/gram. Very reasonable prices for the centre (actually, even better than where I live, outside the ring.) I can't really recommend any other shop. Every other place near the RLD seems like a rip-off to me.
