SaaS Pricing Question: Someone willing to buy at $99, not $299. What do you do?

So, we operate an early stage B2B SaaS. We price the product at $299 per month.

Someone shows interest in your product and really wants to buy; but they are offering $99/mo.

You know that you can offer them a stripped-down version with limited features for the price they are asking.

But at the same time, you know that the ones who bought for $99 have churned in the past.

What do you do?

Option A: Offer them stripped-down version at $99/mo
Option B: Politely decline.
Option C: Offer limited time discount and offer at $199 - which is likely to result into a 'no'.

PS: Feel free to suggest any other way you'd approach this.
