Ok, look I don't know how to describe this but I found it in "Tokopedia" the "Amazon" of Indonesia apparently, there are many retailers in that website in which every one of them has a profile, like Instagram or every social media ever it has something called followers, so the retailer is selling in that website, okay? Now about the price, in American Dollars apparently it's $128.78 which translates to IDR 1.829.000 just check it out:Where did you find this DEAL ? List the website/source. Verify the source, then only we can comment on this issue, whether it's a genuine or a fake GPU, or maybe some other MODEL.
After Nvidia released the 1660, AMD dropped their prices in SEA, like in Aus, Malaysia, Singapore etc. while they did that much long ago in the US n such. Besides, Newegg is selling it for 120 bucks now I think. So it should be legit.Looks legit to me. But you should definitely also ask the retailer, why the card is selling at a slightly lower price in your country.
