If you find a fragrance you like, stick with that. If cost is a factor, buy SAMPLES of the same thing from other sources to see how they compare before buying in large quantities. I bought a fragrance from 3 different suppliers. The first one I bought was just a sample. I really liked the fragrance, but since I was ordering other things from a different supplier, I decided to go ahead and order it from them instead. That was a mistake. It didn't smell anything like the sample I got from the other company. Later, I saw Tony's had the "same" FO on sale, and Tony's ususally has very good FO's in my experience, so I ordered a pound of it from them. That was another mistake. So now I'm out all of that money because I was too cheap to order it from the original place to begin with! Remember, samples, samples, samples! It may seem expensive up front, but it will save money in the longrun.
