​I have a sale until Halloween. Customer wants to place an order and pay after Halloween. What price do I give them?

Basically the title. I have 25% off on orders until 11/1/24. A customer emailed me saying they want me to create their order and then pay me later in November.

I plan to tell her that if she can pay before 11/1 then I’d give her the discount but if she pays after the sale, she would pay full price.

It’s that the right way to go? Or do I just give the sale price cuz she asked for an order during the sale timeframe?

Thanks
