Why you need a few of them? GPU mining is completely dead.

Try different countries - there will be delivery cost, but it will not be so comparable to the price.

For machine learning, self funding my startup and can't afford the expensive server grade gpus. Other countries are usually above msrp + shipping + import tax, would be cheaper to buy from a scalper.

Depending on the country you could try to find a hardware swap subreddit. Mining RTX 3090 (not the one that you mentioned but still) often go for <1000 CAD so you could get 2.5 RTX 3090 for each RTX 4090 you wanted.

There are plenty of 3090s on craigslist as well, fairly common to find below 800$, but 4090s are more power efficient and it's easier to manage a single rig with 7 gpus than trying to network 2 rigs with 14 gpus total. It's also faster for inference without any model change.
