Is it worth paying 90 AUD to upgrade the laptop’s 512 GB M.2 2242 PCIe Gen4 TLC SSD to 1 TB, or would it be better to buy a 1 TB SSD myself and and save the 512 GB for future use?

Also, is it worth paying $150 to upgrade from the included 16 GB DDR5-5600 MT/s (SODIMM) to 32 GB (2 × 16 GB) when buying the laptop?

I’d also appreciate any recommendations on where to buy the cheapest RAM and SSD.

Thanks in advance for any advice or input!
