ASUS VivoBook F512, 15.6” FHD, Ryzen 5 3500U, 8GB RAM, 256GB PCIe SSD, F512DA-EB51, $470

I did not see this, but it seems about $100 from the last post here. With Amazon Prime, it is $469.89.
For some reason, Amex promotion only offers about $22 for this product.
Ryzen 5 3500U and 256 GB PCI-e SSD, sounds good for someone who needs a laptop at this price range.
RAM: "4 GB DDR4 2400MHz SDRAM Onboard memory, 1 x SO-DIMM socket for expansion, up to 12 GB SDRAM"
Therefore, 8GB=4GB (onboard) + 4GB (expandable)?
