Well differences in oppinion make the world go round I guess. I know that when it comes to Purchasenet I'd rather take a hit with extra product over telling a shop I cant get it for them. I'd love to be sold out at the end of a holiday but I am always left with a few cases of most of my line. I usually buy 10-15% more than projected sales on roses and carns and Lilies, and then about 7-8% on secondary focals as well as fillers.
I stagger the shipments so that I am always shipping fresh product, and this way what i am left with still has some life on it, at the end of the week though, if its a loss, I chalk it up as atleast i didnt say no. Do I loose out, yeah every once in a while, but never by more than 5 or so cases of each variety.
Though to a shop I am sure that hurts a lot more, than it does to a wholesaler. And don't worry, I'm not gonna pull that "you can always just have a sale" card that you may hear from consultants, reps or customer service, because, trust me I understand that a depletion sale can wind up costing you money in the long run, between labor, advertising and the fillers you would need to use to create bqts with all those extra roses, unless you just sell them with out greens/gyp/wax or the like, but then again, its still the labor of cleaning, the cost of designing and such.
But like I said, what works for me may not always be good for a shop.
