Bundles can be a great deal or a trap. You see "Device + 2 cartridges + carrying case" for $99, and it sounds like a steal. But if you don't need the case or the cartridges, you're paying for stuff that'll sit in a drawer. Check what the recipient actually uses. If they have their own cartridges, a bare device might be all they need.

Another trick: some bundles include low-quality accessories to make the price look better. A cheap case might fall apart in a week. Look at the components separately. Would you buy each piece at the bundle price? If not, skip it.
