I have two questions concerning GPS's. I am trying to get a TomTom 920/920T or 930/930T. ANY comments or opinions would be greatly appreciated. 1)Will there be a big discount on GPS's? (better than (currently)Amazon's $100 off list price on the TomTom 930) 2)Are GPS's popular items, especially the more expensive ones, that get sold out really fast? (aka do I have to show up at the store like 8pm the day before)
