Tiger Direct has a 1GB Memorex TravelDrive that includes CA Internet Security for $90 with an $85 mail-in-rebate. There is always mixed reviews about Tiger Direct mail-in-rebates, so take this one with a grain of salt.
Other than the risqu mail-in-rebate, this is a pretty damn good deal. Five bones for a 1GB flash drive? Hell yes. The rebate expires on October 31. I would jump on this deal, but I already have a good flash drive that can even withstand being peed on.
