Why is the price so low? Is there an underlying flaw, is the seller desperate for cash, was it merely gifted to them and they don’t need it or is it stolen?
Those questions come to mind for me first before getting to the others (which are good btw).
A quick look at swappa shows that this price is unusually low (not that there are 1TB versions currently listed but its a given that any 1TB will be valued higher than 256gb or 512gb versions).
