Another way is through Bisq. A little less user friendly, but it's easy once you do it a couple times. More liquidity and payment options too. With current tx fees it might be expensive-ish though.

You could also buy Monero p2p from LocalMonero and swap it for Bitcoin using trocador.app (exchange aggregator) or choose an exchange off of kycnot.me

Remember for all these methods the cheapest way to buy is by making your own offer and waiting. Usually on the scale of hours to days depending how competitive your prices are.
