Chill. I see what you are saying, but the fact of the matter is that it is much better to have the name and number of the other outlet with the deal and ask if they'd be willing to call to verify in an attempt to price match (they are not obligated to do so, remember) than it is to show them this thread. As FF said, they'll claim it's not reliable source. ...But, that's really just their out.
Outlet employees don't like this thread - at least most of those who know about this thread. Why? Because it creates more work for them. And, it often leads to flurries of phone calls. Maybe some managers care about overall sales numbers and they way a thread like this can help, but the average employee doesn't. If I'm trying to get size run info from an outlet - usually on something like B-grade Jordan retro drops - what I usually say is, "as you can guess, the fact that you have these has been posted on the blogs and websites, if you can let me know what sizes are remaining, I can post them and hopefully it will cut down on the amount of calls you get, as some people looking for certain sizes will know not to call." ...I want to inform the thread, but I position it as doing the store a favor, which is not actually inaccurate either.
This goes back to what I say all that time - sneaker stores don't like sneakerheads. The sneaker dudes think they do because they buy a lot of stuff. But, really, they know how to get the best deals, minimizing the store's profits, and they often pounce on things that would sell anyway. So, most of us really don't do any of these places any favors on the regular. The more obscure the item you are seeking, the better chance you have they will work with you. But, they know when they have a great deal and they know that they don't need to jump through any extra hoops to get those products off.
I've been hunting stuff at outlets for a long time (though not a thoroughly as some), and I think a lot of the long time pillars of this thread will agree that over the years, ordering from outlets has gotten a lot harder, not just in terms of demand, but in terms of policy. (Remember free shipping for mentioning that you used Nikefind?). And, part of that is that tons of people don't know how to act and wind up making phone orders more trouble than they are worth to a lot of these places. So, I'm actually very conscious of making the stores and employees feel comfortable and happy, and letting them know I'm trying to help them as much as possible too. In general, we should be thinking about preserving this resource in addition to milking it.
...This is not all directed at you; just sort of some food for thought.
