Did you know that one of the cheapest ways to get a gym membership isn't by playing hard to get with the gym membership sales rep, but by purchasing a membership online through Costco? Neither did I.

Sometimes the discounts are so good that you'll instantly recoup your membership fee and still come out ahead.
