I want to say that if you want the new offer, confirm it to me so we can register the appliances.

One person makes on offer. The other person either accepts it or rejects it. If you made an offer of some kind the recipient will probably respond soon after receiving the email. If you need a response within a certain time period then you should say exactly that.
