Who knew that holding on to your old unused McDonald's sauces was a worthwhile investment? One eBayer sure discovered the perfect time to sell his old Mulan Szechuan Teriyaki Dipping Sauce (available only back in 1998) and he ended up getting $14,700 as a result. Of course, this wasn't just luck -the sauce is more popular now than ever thanks to Rick and Morty's most recent episode that aired on April Fool's Day.
The team that makes the cartoon even made a petition on Change.org to bring back the sauce and it already has 20,000 signatures. It seems not everyone was willing to wait until McDonald's changed their mind and re-release the sauce though, which is why someone was willing to shell out some serious cash to get their hands on the lost sauce. Since that auction closed, another seller has put up a comparatively affordable listing for another package of the sauce that will only set you back $1,000.
