Running out of inventory before restock

Hi everyone—I’m fortunately enjoying good sales this summer but have found myself unlikely to be able to replenish inventory before running out of stock. I’m hoping it will only be a few days to perhaps a week or two without inventory.

How can I minimize the impact on my ranking so that my sales don’t skip a beat when inventory is back in stock?

How can I prioritize my subscribe and save customers to avoid losing them?

Is there a way to temporarily slow down sales to minimize time out of stock? Just increase prices?

Thanks for any help!
