Email arrives saying parcel will be delivered by packlink SL, "Never
heard of them", I think.

The message looks scrappier than most delivery scams, but I know I *do*
have an ebay delivery due, so I find the packlink website and enter the
tracking number, it says it can't be found.

I copy the unclickable URL from the email and paste it, turns out to be
a "DPD blue" delivery, I always seem to have "red" around here,
presumably packlink is some sort of parcel aggregator, but 10 out of 10
for making themselves look dodgy ...
