Want an iPhone 4 bargain?

[From Eric Mann] Want an iPhone 4 bargain? "Remember that Radio Shack sale that offered the iPhone 4 for $149 and caused a nationwide shortage in the Shack's retail stores? Well, Sam's Club is about to one-up Radio Shack with a Member-only promotion that drops the price of the iPhone 4 to $147 with a two-year customer agreement. The leaked internal communication suggests the promotion is available now and extends until Christmas day."
