Welcome Alcd!
The reason for the prices of these products is explained in this thread. If you do not totally understand and need to ask further questions about the pricing you can go into that same thread to clear things up.
The other questions that you have can be answered by reading the thread in my signature introducing you to pheromones.
For what to start up with I suggest these :
Ammunition -----> Confidence boast and to give of that strong , sexual vibe
Instant shine ------> Make you feel calm , refreshed and give of that youthful vibe that draws ppl to you.
Together they make a killer combo for attraction
