How can I do to change prices

I have a price column in the product table.what I need is, to give discount of 200 now may be 2 hours,after that it should comes to the original this can be done.

I don’t think that is possible.

Since Glide can’t use a computed column as the price when you’re using Stripe, my suggestion is to have this built in the google sheet formula.
As long as the discount is not user specific, you could have a google script that’s time based that changes the price in the sheet after certain time.
