I was looking for a 5.1 system and stumbled upon this https://www.amazon.com/dp/B00EO976H8 system. I recently installed a Chrome plugin called Wikibuy, and it said I could save more than $800 if I buy it from them. Not sure who the actual seller is behind it, and I am not even sure how to talk to the seller if anything goes wrong.
But $800 saving makes this very tempting. Anyone used wikibuy before?
