Greed? Not really. Since I buy in bulk with discounts I do resell them to at least break even. Greed is a strong word! lol
The greedy ones are the resellers who buy and sell solely for profits and puts a lot of mark up on their prices! they know who they are! 
Is it their fault that idiots will pay $100 for a deck that sold for $5 the week before? If recent trends are any indication, prices only drop anyway. A decade from now I bet anything that the LTD decks will cost $10 or less, if not be completely worthless. I've hypothesized this before, but I firmly believe that company decks will not retain their value, because as more companies arise, there is less desire to own every release from just one of them. A few years ago it was pretty easy owning every limited company deck. E had three and T11 had two or three. David Blaine and D&D had a couple and that was pretty much it.
Now people are looking at the countless new releases and treating them the same as they did years ago.
It just doesn't work.
When every release now is as limited as the Gold Arcanes, and every company doing the <1000 deck "special" editions, it's becoming very apparent that the bubble is close to bursting.
The best lesson I learned in collecting decks is that you should sit down and figure out -exactly- what you want your collection to consist of. Make a list of every deck you want, and in what quantity. Then buy only those. Add to that list the new releases that you really want, that you know you'll want to show off to people, etc.
So next month when there are 15 new KS projects, 20 new big company decks, and 500 small company decks coming out, it'd be pretty easy to ignore them, and focus on what is special to you.
Always remember that it should be special to you, and not someone else.Also, if you want to save money, buy from people on the forums, on FB, etc. Scour eBay for good deals. Never buy from resellers that clearly mark up their prices.
In fact, ignoring big buck wholesalers completely saved me hundreds. I only bother with them when they have special deals or come in contact with uber rare decks (Ace King, Fullboatdealer and Pokerstud52 often have sales/rarities).
On the flipside when I started out, I lost hundreds by buying from wholesalers because it was simply put, easier. I'd buy an Absolut Vodka deck for $40 from them, when some guy on UC would be selling them for $20 a pop. Eagerness and impatience gets us nowhere.
