Subscriptions And Books: This is not a financial gift per se, but the gift of knowledge is powerful. You may gift your sister subscriptions to any financial newspaper so that she develops a reading habit and learns valuable financial lessons. All newspapers have various subscription plans that can be accessed from the phone and the laptop. You can also gift your sister a host of personal finance books, either a physical copy or for her to read on a Kindle or any other device. There are some wonderful books out there that are good to read and teach us solid financial wisdom.
