A Few More Forgotten Orders For Penofin Deck Stain

I just finished placing my order for the penofin deck stain that we will need for the month and told my boss. Of course, he forgot to give me the papers for the four other decks that he booked that will also need penofin deck stain.I take the estimate forms that have been signed and accepted every week and then place one big order for all the penofin deck stain for the month. It is usually about the same but it seems that we have a few extra jobs this month than we normally do. I  am wondering if I call the penofin people if they can just add it on to the online order that I just placed.
