I received an email from Amex offering me an upgrade to Business Platinum from my standard Business Gold card. I accepted the upgrade and they replied with an instant approval. But here's my question: They also said that I should receive my new Platinum card in about 7 days in a white envelope. Is that correct? I thought Amex sends their Platinum cards in a nice welcome package box. I also thought moving up to Platinum is a big deal (like the annual fee of $450) to them so the delivery would be in something other than a "white envelope". I was just curious because it really doesn't matter. I'm ecstatic with the upgrade. Wow! Finally made Platinum!!
