If you're that worried about choosing the right one, try it on your skin and not on a card. This way you get to see how it settles and how well it lasts. Perfumes smell different on different people, all to do with the balance of oils in our skin.
I digress... If you were to try one on each wrist tomorrow and a different two another day you should be able to make a good decision.
I love perfume but I usually smell them a few times before I commit to buying. That's why I hate getting it as a gift.... the majority of the time they never choose right :| lol
