Yes and No. This is a product based opportunity and the way you make money is through the sales of product. However, there is no personal selling, telling or explaining that you have to personally do because the system does it for you.
I've been to about 6 weddings in the past year, and none of them actually did the bouquet toss. I thought it was a nice classy touch to each wedding. I really can't stand the bouquet and garter toss, so it's been nice to see a bit more class added back in to the ceremony.
The bachelorette party is not a gift party in the same way a bridal shower is, so presents aren't necessary. That said, this is a great opportunity for guests to give the bride silly gifts (or even sexy ones like the lingerie that was just too risquÃ© for the shower!).
