Maybe he lives in a part of the world where $50-100 just for a hardware wallet is considered a huge amount of money and the amount he plans on storing there doesn't even cover the costs of purchasing one. Who knows.
Unless you have an old laptop somewhere that you can use as cold storage as some users already suggested, you are left with the option of creating a paper wallet where you can send your Bitcoin. Electrum would be the software wallet I can suggest you.
