It is always fun to dissect these scams. There's an interesting e-commerce scam prevalent in India that popped up as the country embraced e-commerce without much credit card infrastructure in place (most online orders are paid to the delivery person in cash) https://simility.com/delivery-fraud:
"The fraudster businesses ordered hundreds of products from the victim’s website to be delivered on a daily basis. Meanwhile, if customers came into their store asking for an out-of-stock product, they were told it would be in stock later that day. Then the fraudsters paid the delivery person in cash for the small fraction of products they had pre-sold to customers, while returning the vast majority of unsold products without paying for them at the cost of the e-commerce company, thus completing the delivery fraud cycle."
