Allow us to buy extra credits in packs.

Can you please let us purchase additional credits in some form of packs? When we run out, I'd love to be able to spend $20 to get 100 more credits to keep doing things until my next month replenishes. I have annual plan, I don't want to spend $900 to go to next annual plan. I could just use 100 more credits to keep doing my thing. I see many people buying these. This way I end up spending $20-40 on Claude so I could keep doing dev work. This is a feature where you're missing out on a lot of $$$.
