última oferta
Last Friday in Spanish is: el viernes pasado.
The verb is "ofrecer." If you were to say "The offer," it would be "la oferta."
este último
Por último pero no menos is the best way to say "last but not least" in Spanish.
Offer valid while stocks last
In truth, Its simply: The last airbender, with a spanish accent. Checked it on google translate.
