Laptop

On a mission to purchase a Laptop. Must be new, must have WinXP, must have at least a 15-inch screen, must be available on or before this coming SUNDAY. Oh, and must be under or close to $300 :(

All my options so far meet maybe 3 out of the 5 criteria.

Any suggestions? Where would YOU go to get the clearance computers from 3 years ago?
