Why, because it's clearly posted in the For Sale/Trade Rules (please take a minute to read them) - this is done for the protection of the buyer. To many times I've seen someone who says they can get a good deal on something, then the buyer sends their money and then that item is sold out. Now your holding the money and the buyer has nothing just waiting for this hot deal to get back in stock. Along with that I don't want to verify what you say is true each time someone posts threads like this.
If you know where to get a good deal on this item then create a new thread stating where to get them - there is absolutely no reason to have members email you. This thread is now closed!
