I did that only once. Terre d'Hermes is hyped on this site by many so I went to Nordstrom's to try it. I liked it but all I got was an orangey smell and little else so I wasn't impressed. I was desperate to get a new fragrance at that time so I went ahead and ordered my bottle directly from Amazon.com. The stuff that I got from Amazon was so much better than the tester that I tried at Nordstrom's that I couldn't believe it. My bottle seemed vibrant and rounder than the crappy tester that's exposed to heat and light at Nordstrom's. There are many more elements that I smelled from my bottle than just the orange smell from the tester of the department store. Funny thing is that I went to two Nordstrom's to try Terre d'Hermes and both of them are past their prime because of the constant exposure to heat and light. I took a chance that time and it paid off but I probably won't do it again with other fragrances unless there's a chance that it can grow on me. I mean, how many times have people tried a fragrance that they thought they liked only to end up disliking it soon after? The same goes for not liking a fragrance much but there's a chance that it can grow on you.
