Just in case: you can get a .com for less than that nowadays, sometimes $3 for the first year (then transfer it back and forth for $5–7). Here are some price comparisons: https://tldes.com/com, https://tld-list.com/tld/com

I assume some registrars sell these at a loss and expect to offset that by selling you WordPress Supreme Ultra Enterprise hosting for... $40/yr? No idea how this works.
