Bought the Samsung Evo Select 512GB microSDXC UHS-I U3 during Amazon Pre Black Friday sale. The sale is from Amazon.com, but it is available on Amazon.sg as well.
I got it for S$75.52 with free shipping to Singapore since I am an Amazon Singapore Prime member. The usual price is about S$120 on Amazon, and on Lazada, it is selling for S$174.99.
