Count required purchases before comparing phones
A phone supplied without a mains adaptor may still be the better buy if you already own a compatible safe charger. Conversely, a low headline price can be misleading if a proprietary case, cable or adaptor is immediately required.
Avoid bundle logic
A bundle is not a saving unless every included item is suitable and would otherwise have been bought. Price the phone and each useful accessory separately before accepting the advertised bundle value.
