Do anyone know how often stores receive ships of iPads? I am looking to pick one of in store on the morning of Friday the 22nd, but all locations are out of stock. These locations were some of the first places (that I read/saw) that received stock. They went out of stock on Friday the 15th. I am hoping that another shipment comes in and some are available on this day. Was wondering if anyone knew how often stock is received. Also, if anyone know any retailes that do online to instore pick up for iPads can you please let me know. Thanks!
