As a general rule, I try not to get too excited by anything.
Part of this is due to the standard sort of defense mechanism against disappointment. As the saying goes, a pessimist is either right, or pleasantly surprised. Of course, that often leads to pretty dreary life experiences, so there are certain realms in which I let it all hang out.
But the main reason I strive to keep skepticism high is out of simple and repeated experience: you are always punished for your enthusiasm.
Case in point:
If you will recall, I ended up paying ~$85 for Mass Effect 3: Digital Deluxe Edition about two days ago. Had I waited those two days, I could have spent $16 somewhere, anywhere else. I am not in a financial situation in which the $16 necessarily matters, but it matters to me that I essentially paid an Enthusiasm Tax.
The deal was via Dealzon, and I was made aware of that via Kotaku’s The Moneysaver article. It expires today (March 10), in case you are interested. Then again, I have little doubt that you could wait a month or two and get an even better deal.
Incidentally, based on my ME3 experiences thus far, it is worth waiting for the price drop.
