Sure but you should still hear from the broker in that instance.
"Hey
@WinterSolider, thank you for your offer on Aulani listing #123456. Just to confirm, you're offering $19,000 for 200 points ($95 per point) with the Seller paying 2024 dues and the Buyer paying 2025 dues plus an estimated $950 in closing costs. Please be aware that the Sellers of this contract are traveling with limited internet access, and we expect to have a response from them no later than Monday, September 23."
It's especially important because a lot of these resale companies have crappy websites where you can never be super confident that anyone on the other end actually received your offer after you hit send.
