Best Offer on Galaxy S20 FE 5G

Hi friends!

A bit of a background first, I'm paying Telstra $40 for a prepaid package for free national calls / texts and 20 GB internet. My need is not more than 10 GB per month for the data.

I've seen many experts here posting some cool deals on Galaxy S20 FE etc. Esp. this one (which is not valid now, although it was for S21) -

As I am already spending $40 a month on my plan, I would like to learn from you what's the best (and cheapest) possible way to get Galaxy S20 FE 5G?

p.s. I do have a 20% discount on Samsung Store.

I look forward to your advice.
