The black market for fast-food sauces and why it exists

Ketchup & ranch packets are worth more than you might realize. In fact, there’s an underground resale scene where people trade fast-food sauces online, especially the ones that are rare or seasonal. Even something as simple as a McDonald’s dip sells for big money on eBay. 

Why do these sauces end up on the black market at all? And how did this whole thing even start? Let’s find out.

What the black market actually is

By “black market,” we’re not talking about knockoff sauces or homemade copies. Nope. It’s the resale of actual branded packets that’s become big money. These are sauces that restaurants hand out, but were never meant for sale anywhere else. 

The internet makes this rather simple, since sellers just have to put a packet on an auction site & wait for a fan somewhere else to buy it. Just like that, a sauce changes hands outside the official system.

So what do they sell? Most sellers list sealed packets they got with meals, or tubs connected to limited promotions. However, the most valuable sauces are the ones tied to special events or short-lived drops that were never meant to last.

How this took off in a big way

One moment that really made this resale culture explode was McDonald’s Szechuan Sauce in 2017. The chain brought it back for one day after years in the vault. As a result, fans swarmed stores, but many of them walked away empty-handed. 

Soon enough, packets started appearing online, selling for way more than anyone expected. The newer ones sold for around $30, while one packet of the older sauce from the original 1998 release sold for nearly $15,000. Yes. $15,000.

Since then, every time a chain teases a special dip or limits supply, you see the same cycle repeat. It’s scarcity and hype, followed by frustration & listings online.

You might be wondering why these sauces make it to resale platforms at all. That’s where research comes in. There are a few reasons, including:

  • Scarcity drives behavior. Studies by P. Broeder & other researchers show that when products are only around for a short window, people want them more. 
  • Drops fuel resale. Steele et al.’s operations research found that when stock runs out, a resale market almost always pops up, no matter the industry.
  • Consumers resell on purpose. Kim & Kim’s work on limited editions proved that buyers often plan to flip rare goods when supply is tight.
  • Platforms make it easy. Gray-market research by Deng et al. found that sites like eBay thrive when official supply is cut off or limited.

How collectors and fans drive the whole sauce resale scene

However, not everyone is buying these sauces to eat. Some of them just want to keep them. Collectors treat packets & tubs almost like souvenirs, so they’ll hold onto unopened packets for years by storing them in drawers or keeping them in binders with other branded stuff. A few ketchup packet collectors hold onto sealed sauces like trading cards.

Collectors also like extras. A few sellers include napkins & receipts, along with photos from the day they grabbed the sauce, to make the item feel connected to a specific moment. Such an interest in these sauces makes them into something worth money.

There’s also the crowd that wants a “full set.” For example, if a chain released a new sauce in 2016, another in 2019 & a one-day promo in 2021, certain fans will try their hardest to get each one. 

Enter the resellers.

They know collectors are willing to pay more just to fill the gap, as people chase completeness. That’s true even with items that most others would throw away.

Trust plays a big role, too. Most buyers want proof that the packet is sealed & real, meaning that sellers who upload clear photos of the wrappers & logos tend to get more bids. In fact, they’ll take things further by analyzing the packets to see whether they’ve been refilled or tampered with.

Of course, there’s no official oversight here. Brands don’t organize it & there’s no authority tracking who’s buying what. Instead, it’s just fans & sellers running the black market. Who would’ve thought sauces could be so expensive?
