I figure that will happen from all the calls for penny deals. They probably only got a few calls a year, if that, and now they're getting numerous calls every week. If they don't know already they'll certainly figure out where it all comes from as people have already told / shown HD employee's how to find the deals. It's only a matter of time until someone mentions this site. That info will work up the ladder and at some point they might change the penny policy or fix the computers so it won't show those deals to us. Maybe even take the date off the tags. Lots of ways to make it harder on us. Obviously, by now, they know about SD and Fat Wallet, so I'm sure they're not too worried about deal sites in general.
But, making it harder is why I cringe when I read about some of the phone calls. Sure, getting a penny deal is cool, but if all the deals ended tomorrow was it worth it? I'm perfectly fine with paying the last clearance price on items to have access to future deals. That will save me way more money over the long haul than I'll make off any single penny deal.
The barcode generator post a couple days ago reminded me of a time I went to a friend of a friend's house and he had a new, in box, carpet washer and a new vacuum sitting on the floor. I asked if he was starting a carpet cleaning business and he straight out told me he read online how he could print a barcode for a lower / entry level machine, grab the best one off the rack and stick the new barcode on while wheeling it to the register. Since the screen would come up with "Hoover" or whatever nobody noticed the different model numbers.

He was so happy he saved $100 on these 2 things. I said something like, "I heard you make close to 6 figures? You're willing to lose it all to save a $100?" He never did it again.
The point is, think about the risk vs reward on the deals and choose your battles wisely. Don't raise hell, and potentially screw everyone else, just to save $12 on some bird seed, or whatever.
P.S. I saw that bird seed was on clearance.
