Bought and received a set.  Box looks a little "aged", but the plugs are perfect.  Probably old stock that they're clearing out.  Just placed an order for another set.

FYI: If you order more than 8, the website adds shipping.  Paste the below into your web address bar.  If you use Google, it gives you a different price.
