Ordering things online has become the cultural norm these days. Thanks to services like Amazon, Etsy, and eBay (just to name a few), more and more people are choosing to skip the store and just wait for delivery.

It's not hard to understand why; plenty of these services have competitive prices and can have your order there within a day or two.

Of course, having your things shipped to you still relies on the postal service, which offers its own set of challenges. All too often people have incidents where things are either damaged in transit, lost completely, or are just flat out not what they ordered.

Case and point: a South Carolina woman was eagerly awaiting the delivery of the yoga mat she'd ordered online, but instead the postman brought her something completely unexpected; a box full of oxycodone.

Seriously, this story gets pretty weird...

The as-yet unnamed woman from Rock Hill, SC expected to receive her yoga mat, when she was instead handed a very heavy box that seemed much too big to hold what she'd ordered. Upon opening it, she got quite the surprise when she discovered it was full of illegal oxycodone pills.

She immediately contacted the police, who sent drug agents over to pick up the box and determine where it had come from. They soon revealed that the 20,000 pills of oxycodone found in the box were worth nearly $400,000 in U.S. dollars, and that "Most of this is counterfeit, and it comes from other countries. And it's being shipped in."

York County drug agent Marvin Brown spoke to news outlets soon after, explaining that the package was intentionally sent to the woman's vacant apartment where she previously lived, and only didn't end up there because the local post office knew that she had moved. According to Brown, drug runners tend to have packages shipped to "vacant apartments, homes where people are gone to work for the day, and someone's sitting outside tracking the package, waiting for the trucks to make the delivery."

The York County police department continue to investigate the origins of the package, which had a return address located in Newport Beach, CA.
