Attempted Overpayment Scam

I am a Pampered Chef consultant and I was contacted by someone through the "Find a Consultant" section of the website, she claimed to want to buy about $700 in product from me. The email address she contacted me through was [email protected]. She gave me a shipping address of: 4560 Daisy Reid Ave, Apt 409 Woodbridge, VA 22192.
Her emails had terrible grammar and strange punctuation/capitalization, but at first I thought that perhaps she was just a non-native English speaker. She said she was going to pay with a check that she would mail to me.
After the initial contact, she informed me that her "boss" had "accidentally" sent too much money. She said she would like me to use moneygram to send the excess money to her "art works dealer", then in a follow-up email, she said she wanted me to send it to her "cousin", Benita Carter in Rock Hill, SC. This was when I first realized that something was sketchy with the situation.
She kept telling me that it was urgent that I send the money as soon as the check cleared, so that hospital bills could be paid. I deposited the check before I figured out that it was a scam, but I did not send the money. Especially since she told me in another email that the excess money needed to be sent to Wanda G Tompkins in Vidor, TX. Since this was the third different person that I was told to send the money to, I had definitely strong suspicions that it was a scam. I googled the names she had given me and discovered that Wanda Tompkins has been used in other scams based on a scam watchers website.
I contacted my bank and they said it would be a few days before they would know for certain that the check was fake.
At this point, the scammer had begun texting me multiple times a day, demanding to know what was happening. I informed "her" that the check hadn't cleared and I would let "her" know when it did. She continued to repeat that it was urgent and needed for hospital bills and if I checked, I'd see that it had cleared. I stood my ground.
I just noticed that the check has been returned as fake and am glad that I didn't transfer the money or make the product order because then I would be out $2300.

I'm glad you realized what was going on before you were scammed.

Of course the reason for the urgency is the scammer knows that the longer the wait, the more likely the fraud will be discovered before you send money.

Just one thing I want to make sure you (and readers of this thread) understand, though: a check has not actually cleared when the bank gives you the money.

Not all fraudulent checks are discovered in a few days. Scammers often write checks on stolen account numbers. If the bank account used is a large and active one, or if the account owner simply doesn't monitor the account well, it can actually be weeks before the fraud is identified--and even then the bank can come back at you for the money.

Please post the emails, with complete headers. Strange punctuation and capitalization are often symptoms of writing English while African. The headers can probably tell us for sure. Also if someone else got the same email, she can recognize it as scam.

Don't tell the scammer that you figured out it's a scam. Just stop answering.
