What should I check before buying this product for someone else?

Review whether the purchase can be provided to or used by another person under the stated terms. Avoid choosing a complicated option solely because it has more advertised features.

How can I decide whether an optional addition is useful?

Compare that benefit with your actual intended use. Consider whether you already have an equivalent suitable resource.

What should I compare when the same seller offers a product through different channels?

Ask whether an advertised benefit applies to your intended channel. Compare documented conditions instead of assuming the offers are interchangeable.
