If you’re anything like me, you use Amazon for a good number of purchases each year. It’s convenient, and with Amazon Prime ($79/year), two-day shipping is free (one-day shipping is only $3.99). Wouldn’t it be nice to earn even more points for shopping there anyways than you do already?

For instance, today, I needed to make a purchase on Amazon for roughly $120. Normally, I would’ve earned 120 points on my American Express Gold card, but by purchasing a gift card at a grocery store, I was able to earn 240 points. Same thing would happen if I purchased the gift card at a gas station, since that card gets me two times the point there, as well.

If you’re fortunate enough to have friends or family in the airline industry, you may be familiar with the concept of “Buddy Passes” – virtual flight coupons airline employees can give to friends and family, and allow for travel on a standby basis, nearly free of charge. Often, the only cost to the passenger consists of the taxes and fees of the flight itself plus a service charge determined by the individual airlines. This means one-way flights could conceivably cost no more than what you have in your wallet right now. That said, it’s important to be prepared for your Buddy Pass travel by knowing what to do before you get to the airport.
