We received this message below twice. It's possibly part of a purchasing scam to fish for e-mails or more. I'd be wary of messages like this.
I'm from Singapore and I want to order from you.
Could you ship worldwide to Singapore or Indonesia...???
Could you ship the item by FedEx Delivery...???
Do you accept credit card payment...???
I'm waiting for your next response today. Thanks and have a nice day.
