If they had over 10,000 Receipts showing one or the other winning, This is actually a pretty large poll and I wouldn't expect it to be over 5% error, maybe 10% from that poll. However I'm not sure what there actual sample size was, obvious the bigger the better.

You could have 100,000 receipts, but that doesn't necessarily mean anything if the sample isn't random.

For example, when I used to work retail, I worked in a community with a largely Russian population.  Even when the Wii was dominating and the PS3 was sucking wind, we always had more PS3 sales.  So, if you took receipts from our store, it would give you a really skewed view.  There is no reason to expect it to be accurate to 5% unless you have some knowledge of their sampling method.  Having worked on Black Friday, I can't imagine the sampling method was anything more complex then checking random receipts.

This app would cover the whole country wouldn't it? Anyone can download it. So I'm sure it's pretty random.

Yes, but remember the downloads are for rewards and offers. If these promotion are for the one console in particular then the numbers will obviously be skewed. 

Poin in case, that site had Madden and COD as the top sellers on BF , we know there's no way that's correct, but which gamers usually buys these? This speaks volumes of their sample.
