New External Hard Drive Options

I want to purchase a new external hard drive. I see two options:

• wireless, as described on http://www.howtogeek.com/235283/what-is-a-wireless-hard-drive-and-should-i-get-one/
• wired. This 5 TB external hard drive is on sale for $109 while a 4 TB external hard drive is on sale for $117.99. Is shipping available or not?
