Good luck with your sale, but the way its worded is inviting unnecessary complexity.
If I put a bid in for $99 for the lot, but find that you parted out one of the items, I am going to retract my bid. In fact, with the way its worded, I will be surprised to see bids.
Worst case scenario, you part out everything but the pac man joystick. If I get that and a few buttons, for $99, I'll be dissapointed
Part it out or don't.
