Is hunting deals a really bad "hobby"?

I placed an order this morning for a 500W power supply. Free after Rebate.

Before I place the order, I first checked eBay

for its “reselling” price, then checked tax rate. then checked the review of the “rebate”. I clicked the “place your order” button after I feel that the probability that I will lose money on this deal is less than 0.1.

I made up this 0.1 probability myself. Can’t really pin down the probability” The UPC can be damaged, the power supply can blow, the check can get missing …. Nothing is really zero-probability, I just make up a number to make myself comfortable.

Initially, Yannick did not like my deal-chasing behavior. He considered it as “short-sighted”, “waste of time”, “waste of energy”, “low taste”.

After a long, long time, he finally stopped complaining about my deal chasing, because he finally figured that:
1. I am not chasing the deal, I am chasing the “feeling” of getting a good deal.
2. I may waste some “time”, but I do not waste money. Some times “hot deals” can get really expensive. I do not do those un-nessary deals. I either purchase something we really need, or if somethinge not get used in 3 month, I sell them (except for my clothing). I always check “resell” price before I make a purchase. And I almost buy things online, I do not evey pay gas for it!
3. Getting a good deal is a hobby to me now! It relaxes me from my boring work, gives me a tiney, yet sweet feeling of “achievement”.

Overall, getting a good deal is now (1) an inexpensive-hobby; (2) a good after dinner entertainment; (3) helping build frugal living style — why stopping me?

Now, Yannick encourages me to be a shopper! As long as I am a shopper that brings in money and decrease budget, as long as I am a shopper who are happy over the deals I am making, he is a happy too. Win-win situation!

Not sure how many shoppers out there are like me. Maybe I should start a deal chasing blog myself, and get more friends in the circle!
