The first question is all about leveraging your time. For example, let's pretend that I get paid $50 an hour and it takes me three hours to rake the yard. The neighbor kid would be happy to rake the yard for $50.
Now, the question most people would ask is, "Is it worth $50 for me to have someone else rake the yard?" This is a simple question of supply and demand, but it is not the question you should be asking yourself if you are an Internet marketer.
Instead, you should ask yourself, "Will this save me more time than it costs to pay for it?" In this case, you would make $150 by working 3 hours and pay $50 to someone else. If you have the neighbor kid rake your yard, you have just earned an extra $100. This is because you have just used your time more wisely. While you could have raked the yard for free, those are 3 hours you cannot work. You would have made no money and had to rake a bunch of leaves. If you pay the neighbor kid $50, you net $100 increased earning and do work that pays you instead of raking.
Work and no pay vs. paid work - it's an easy decision for Internet Marketers to make because you can work anytime, but this requires a bit of a change in thinking. Therefore, if a product or service online will save you a lot more time than it costs to pay for it, it is an easy purchase IF you will actually use it enough for it to pay for itself.
2) Will I actually use the product enough to justify the cost?
