I am curious about where you get your products. I usually just go through the local nurseyman to get my fertilizations products and he knocks off 25% from the sticker price..but I still think that its way to high. I was wondering: how many of you go through the manufactor instead of the dealer? about how much cheaper is it? about what are the costs involved in doing it that way? Like is there a minimum that you have to order or what.
