What a thought! I think this is one of the best guerrilla marketing I have seen. Imagine a man opened a Facebook page and innocently declared that he decided to give everything away. Reason of giving was that morning he just felt like giving away everything what he had in his house & the guy also showcased videos of all the products he owned.
After getting huge number of fans, getting covered on the front page of the newspapers & people queuing up at his house he revealed that the reason for his generosity is that Homecenter was opeining its Sales Season.
I think to do something like this in any market (this was done in Colombian market) needs lots of guts coz if it fails then there is no way to save it.
Have a look at the video:
