My advise is:
First you go to your Macy's, Sephora or Nordstorm or some mall that sell fragraces at your place to try out some fragrances (try on the test strip first, then try the ones that you think you might like on your skin, maximum 3 fragrances each time, wait at least 8 hours to get the whole experience/development of the fragrances) - trust me this will take weeks to find out which ones you really like.
So let's say you find the particular fragrance that you like then go to your local TJMAXX, Marshall or go to online dealer (I only trust Amazon.com, the ones that "shipped by and sold by Amazon.com") to see if it's available at your affortable price.
Personally I never pay full price for a fragrance (about $75 I think). I did get the Hugo Energise for $23 or Lolita Lempicka au Masculine Fraicheur for $26. With a budget around $25, you can get a lot of designer stuff like Calvin Klein, Hugo Boss, etc.
And one more thing, there's no best fragrance out there. There is only the one that suit you best and you feel good wearing it. I encounter many fragrances that too expensive and considered a masterpiece by many people but to me they're just a waste of time and money. So IMO, in the fragrance world, especially for you or me - 3 months ago, I say new comers, your opinion is the most important opinion
. But do consider the fragrance reviews here though, they'll help you spot out which one you should try first.
Ah, do not buy blind (buy without trying on your skin and let the fragrance develop for at least 8hrs) or you'll regret it, big time.
Hope you'll find your fragrance soon
