In most cases gift cards should not be thought of as cash – they tend to lose value quickly, and you often can’t spend the last few bucks on your card. However, there is one case where you should think of them as cash – when you send them through the mail. Every week I see stories about Postal employees being busted for stealing gift cards from the mail. If you do want to send gift cards through the Postal mail, don’t make them look like gift cards.
