I have no idea why they decided to make this FP
this is a YMMV deal -- not a national one
It's the FP attention that's caused many retailers to catch on
I put YMMV in the title, but it is a national deal. I've seen people in this thread from across the country have success using this coupon. Worse case scenario, they were able to get it price-matched at Best Buy, Office Depot, Staples, or in some cases, Walmart.
With the exception of a few areas, like Texas, where district managers decided to make their own rules... people used it without issue. I think the bigger problem was actually finding a store with stock available... that's why people had to resort to competitors.
As for it making the FP, yes, it brought greater attention to the deal... but it's not like this was the only site that copied the deal. Several other deal sites had it copied within a few hours of me posting it. It even made it on national tech sites, like Gizmodo's Deals of the Day.
