It's not entirely obvious from OP's link, but it appears this offering is from 2005 or earlier (see this page listed in the "News" section: http://www.biyubi.com/computadora.html)

I think it is entirely obvious that they're not trying to sell anything for $99 in 2021.

Amusingly though the footer copyright is to 2020. (i.e. it's not automatic, and is as recent as that.)

If the date is server side script you cant tell if its automatic or not.

If the date is 2021 and it says 2020, I can at least tell that if it's automatic it doesn't work.
