Hey, thought that $99.99 Amazon deal for a Palm Pre was really snazzy? Well today, Walmart appears to go one better by cutting the smartphone's price down to a staggering $79.99 (on contract and with mail-in rebate). If prices keep going this low, you can probably expect the Pixi to show up for about nothing (zero, zip, zilch) sooner rather than later. If you've been looking for a deal to get into the Pre, this is it but too bad if you dropped $200 a few months ago.[Via everythingpre
