Online selling may have revolutionized the shopping industry, but buyers beware: scammers are still everywhere. Just ask this 21-year old woman from Brisbane, Australia, who placed an add on Gumtree, a Craiglist like classified listing site, to express interest in buying a number of new or used iPhones. Apparently, however, the woman didn’t take the right precautions to assure she was buying the right Apple products.

The Herald Sun reports that soon after the woman placed her listing, she received a phone call from a female seller who claimed she had two iPhones available for sale. The two negotiated, agreed on a $1,500 price tag, and then scheduled a meeting at a local McDonald’s to make the exchange. The Brisbane woman’s big blunder? She didn’t open up the iPhone boxes before letting the seller get out of sight with her money. According to the buyer, the boxes looked new and she wasn’t suspicious. When she got home and opened the boxes, however, she realized that she hadn’t bought two Apple phones, but actual apple fruit. Apparently, the seller had filled the boxes with apples to weigh them down, then taken the gamble that her buyer wouldn’t open the boxes to check the product. Sadly, the Brisbane woman took the bait.

Jess Hopkin, the Senior Constable in charge of the case, won’t be able to do much to track down the culprit, who didn’t provide any personal information and probably used a phone that is now disconnected. However, she did provide some cautionary words of wisdom to people who want to conduct transactions over the internet. For those who spend a lot of time online or frequently use sites like Craigslist or Gumtree, the advice has likely been repeated a thousand times.

“Don’t stay away [from internet shopping sites], because most people are doing the right thing, but be smart about what you buy,” Hopkin told the Herald Sun. She also warned online shoppers that, “if something seems too good to be true, it probably is,” a common mantra used to point out scams, and that common sense is the best weapon any internet user has at their disposal.

Hopkin also stressed that it is imperative for scam victims to report the crime to the police. In many cases, a scam victim will stay silent and simply accept the monetary blow because they are too embarrassed to open up about the situation to anyone else. Embarrassed or not, however, a scam victim should alert both the authorities and the site where the scam took place. Who knows, a single tip-off may be the difference between a scammer getting caught and going on to cheat dozens more people out of their money.
