I think the point was that people care about ppd, not ppi. 218 ppi would be too low if the screen is 1 inch from your eye or too high if it’s 100 inches from your eye.
A similar thing actually happened to me. I was receiving a small package (probably a phone case) about once every few weeks while living in a rental house.
The seller had put my address as their address, so all undeliverable mail came to my house.
I brought a bag full of these packages to the post office, explained the situation and gave them the packages. The entire pile of packages ended up back at my house a few days later.
I found the seller on Amazon and messaged them:
———
Me: I haven't ordered anything from you. I have received 6 packages that you sent but ended up at my house because the return address that you used is my address, not your address. Could you use a different return address?
Seller: Dear nulltype, We're sorry about this, we can't change the address at the moment because of the cumbersome policies on Amazon, but we'll change it when we have a new production facility. Please forgive us. You are free to use the packages. Sincerely,
