these monitors were a one time buy special for Office Depot, they ran in a weekly ad about a month and a half back... something like $250 after MIR at that time, each store got so many in before that week, and then the monitor was essentially discontinued as soon as it was recieved. it just took until now for it to drop in price and make people go crazy.
ALWAYS call the store if you can, unfortunately the "order online" system for OD isn't very efficent. You place an order and even pay for it, but then it can take a few hours to make it to the store, then it has to be printed out ... in that ammout of time it's easy for someone else to just walk in and buy one.
also to hijack and cause a new round of Office Depot fun... check you local store for the sony cyber-shot T1. just reduced to $199.99 to make way for the T7
