TP-LINK Wireless Router

I have a redundant barely used router to dispose of Specs are :-

TP-LINK 300 Mbps Wireless N Router. Model No. TL-WR841N

It is in the original Amazon packing and available for the price of postage. I don’t know what postage will be or what would be the best method of posting, PO or Courier ?

take care
