I determined that one store in my area had three units per week delivered, all arriving on Wednesdays and put out on display by 9am that day. Being there right at the moment the units are put on display will aid in getting a unit. Their units were gone in minutes of being placed out. You will pay retail prices if you succeed with this method. Approach all the retail outlets in your area with this strategy.
Persistence has a way of paying off.
If the retail stores in your area are not first come, first serve, but will put you on a waiting list, get yourself on the list. You can always remove yourself should you obtain a unit using one of the other ideas here. Befriending a sales clerk in stores with waiting lists may help you here. It can never hurt. Turn to the Internet for help with finding a unit.
