I went into my store (Sterling, VA) at 11am when they opened. Went over to the PS3 isle and there were no black controllers to be found. Bummed, I started looking at the end caps and finally the Demo area, where I found a stack of them! Took one to the front register and told the guy "I heard about your new Low Price Guarantee policy that started today" and he said yep, "Frys.com, one of the merchants you have listed, has this on sale for 19.99" I showed him my phone, I let him know it was listed for in-store purchase only and I was in-store at best buy. He wasn't exactly sure how the new policy worked so he went to speak with his manager. After a few mins of talking, they said yes, the price match is within the new policy since frys.com is part of their approved merchants to pricematch. I was limited to only getting the black version and I was only able to get one according to their new price match guarantee..
Ill upload a copy of my receipt in a bit...
