I know that the Games Workshop store in my local area has limited hours, but then again one man stores it seems only logical. So this came in, that stores may be testing to keep them open more days per week.
Please add a little salt to this, but would not surprise me.

Not sure if you heard of this or not yet; see post about staying open 7 days a week from local GW store. I heard that this is test at a handful of store within the US.
