These are the methods that I have implemented to help disseminate the deals that I find:
For Amazon deals, I update the
ToolGuyd "Amazon astore" on a regular basis, via the "DealGuyd alerts" category. The way the astore works, you add a product to your cart, and when you click "proceed to checkout," the product is added to your amazon.com shopping cart. I figured that this might be a good way to revolve the 9 or 18 best Amazon deal finds.
For non-Amazon deal finds that I post about on ToolGuyd, there is an
email alert subscription service. After I post about a deal, an email is automatically sent out the next morning at about 9-11am EST.
For those that don't want to bother with emails, there is a
link to the DealGuyd category for reference purposes.
beelsr,
In an ideal world, your suggestion is a good one. However, this is not a perfect world, and you cannot trust a community's discipline to adhere to the rules you propose. Almost every time I see post restrictions such as "alerts" or "new deals" only implemented in a forum thread, stray posts and comments eventually result to a moderator closing the thread, or turning it into an updated-by-mods-only thread.
Second of all, a "deal" to one person may not be a deal at all. Over on slickdeals, there are countless threads which mention crappy or regularly priced tools. It might only take a few such updates before people unsubscribe.
