The economy friend. At least that is my theory. Prices for materials and such are higher, especially if there are not as many people buying as there used to be. Things will taper out. I am amazed at the fact that a small company like AD is still moving along in it’s business in the current economic environment; a testament to it’s strong leadership, I imagine.
In the meantime, get the To-Go bottles. There are approx. 40 or so odd sprays in each bottle, enough to test for two weeks per bottle at 3 sprays per day. That way you can try the product, and if you like it, save and purchase the larger bottles for your usage.
Here’s a review I did 4 years ago when I first tested P74. Good times 
Also, do a forum search for P74, and read up on the experience of others. For me, it is about Focus, Fun, and Connection. Very enjoyable.
