Here's how to make it simple and succinct:
You: "Hi, *Distributor Name Here*. I'm interested in MBr. Do you have one in stock?"
Them: "Yes. CE, SE, and 1 LE left"
You: "What are the Pinside prices?"
Them: "$5999, $7299, $8399" (made up for this example)
You: "Great! Can I pay with card?"
Them: "Yep!"
You: "I'll take MBr SE."
Them: "Fantastic choice!"
*card info is exchanged*
Them: "Thank you for your business! Your game should arrive next week. Enjoy it!!"
*1 week later, you have your game. Life is good.*
Don't obfuscate it.
