Visa Gift Card
Some of these shady life hacks are immoral but not illegal. However, there’s no denying that the following tip is stealing. But it’s also fascinating to see what people will do or try to save a few bucks. The Redditor recommends using a Visa Gift Card to save cash on offline purchases. Yes, it’s genius but it could get them in a lot of trouble.

This is a big risk but there is plausible deniability if somebody realizes it. The problem is that it is becoming more difficult to use this life hack. These days airplanes have wifi connections and airlines are smarter. They may reject gift cards or immediately process payments so exercise care or it will backfire (via slantview).
