It looks like with the walmart option you get Topo USA version 7. DeLorme offers all kinds of ongoing deals for the PN-40/Topo USA version 8 bundle. If that is the one you want to get I would call them and work a deal over the phone. I got the bundle for something like $299. Still more than walmart but you get the newer Topo USA. If you, or anyone, does get this particular mapping software I would suggest doing the subscription for the topo/aerial/satellite downloads. Well worth it if you want to map out large areas.
