Quoted from Otaku:Then there was about 10 seconds of silence as I waited for him to offer some sort of alternative or opportunity for me to apologize but obviously there was none, so I said "Okay." and then hung up.
It sounds like that was your opportunity to apologize.
I wouldn't worry too much about it. I'd say you could try to order again later and they would let you. Just try to figure out if you want it shipped or picked up and stick with it, especially with such a large order. Also mail the check same day as you place the order.
Edit: It sounds like Forceflow has the process figured out. That makes me think maybe you should have asked here how to place an order with them. I know I will be learning from your mistakes.
Quoted from Otaku:how to order so "old school" and just not wanting to deal with the overcomplicatedness
It's not really that complicated. Have a part number and mail a check. You should have checks if you have a bank account.
