Look what’s on sale! Nice pay what you want. Never hurts to have another copy?
Keep in mind that this copy (supposedly) needs to be registered within 30 days.
If you plan to gift it someday, you can open a new copy of RW in the guest account of your mac, register it with a different email address than the one your current copy of RW is registered with…and then give the registration details to someone else down the road.
