Fragrances you are glad you didn't blind buy, and ones you regret?

I was going to blind buy Diptyque Fleur de Peau but managed to get a sniff of it in a store (hard to do for many fragrances where I am)... turns out while I like the smell a lot, it hangs on me for like a full 12 hours and everyone knows about it.

Is there a fragrance you were going to blind buy, but something thankfully turned you off it last minute? And what are your blind buy horror stories?
