An internal memo from RadioShack (recently re-branded 'The Shack'), shows they will be selling the Palm Pre this weekend, August 7-9 for $149.99 for new Sprint customers, with a two-year contract and at a minimum, Sprint's Everything Data Plan. Current customers will have to pony up $219.99 ($20 more then dealing with Sprint directly according to PreCentral) for the device. Great way to save a little on the device if you've been meaning to get one and don't mind switching to Sprint

The latest amongst retailers vying for Pre business from Wirefly to Amazon.
