A couple years ago I did a similar thing. Wanted a new bike for both my wife and I. Looked at a few brands in the style I wanted and compared prices. I involved my wife in the process since I wanted to ride with her. Test drove (rode?) a few and made the decision based on the feel of the bike and the service reputation of the bike shop since I’m not smart enough to work on it myself. My conclusion was that there wasn’t much difference between name brand bikes in the similar price range, just minor advantages/disadvantages depending on personal preferences. So, if you like the Giant and it’s discounted 15%, buy it. But, if you’re only buying it because of the discount you may regret it later when it sits in the garage unused if you really don’t like it as much as another similar bike from a different manufacturer. Just my 2 cents.
