If you've ever purchased anything online (domain names, webhosting, etc.) you've probably noticed that most companies offer discounts if you buy in bulk or select the yearly subscription feature. But how many of us actually put up the extra cash now and use these features, in order to save more in the future? I personally try and do this whenever possible.
I did a pretty comprehensive post here about this exact subject.
If you have the money to put up now, and you opt-in to buy say, 6 domain names from GoDaddy at once, or a year worth of hosting from whatever company you choose, you can save a pretty significant amount of money right away!
