I recently posted a baby item for auction and after a few hours, I received an inquiry from a certain Melissa saying that she's from a reseller company named ONE WAY . Basically, she's offering me a way to make money. Here's how it goes:

I will receive packages. They have their own USPS account and will pay for shipping and email me shipping label (I will need to print it out and put on the box). I will go to USPS store and ship package within 1-2 days. They will pay me money for my work via Paypal or via personal check: Small packages and letters - 20$ per package Big packages >10 lbs - 30$ per package.

Has anybody tried this yet or is this a scam?
