With a nod to Jimmy McMillan, this will no doubt be the common refrain among students this week as they come back from winter break and have to purchase all new textbooks at incredibly inflated prices. We pity the science majors.

It’s appalling, really: According to College Board, the average student at a four-year public college spends $1,200 on textbooks per year (!!!).

But now, thanks to two savvy college grads, cash-strapped students may never have to spend that kind of money again.

Entrepreneurs Peter Frank and Ben Halpern launched a simple Google Chrome plug-in last week called Occupy the Bookstore. It allows students to compare prices for textbooks directly on their school bookstore websites.

This means students can automatically see what a textbook costs on competitor sites like Amazon and Chegg before being forced into paying the full list price. The extension’s price-comparison engine even displays a range of editions, including new, rental and used, saving students an average of 70 percent off the bookstore cost.

“We think it could be a great tool for students to save a lot of money,” says Frank in a phone interview.

In very millennial fashion, the co-owners first met on Reddit. As recent grads, they were all too familiar with the insane prices of college textbooks, so in 2013 they launched Texts.com, a textbook exchange site that allows students from virtually any university to buy and sell books from one semester to the next. The plug-in is an offshoot of that idea.

“We’re 2012 grads, so we’re really just scratching our own itch,” Frank says. “We knew this was a problem, and we wanted to fix it.”

Their ultimate goal, they iterate, is to help students become informed consumers in a bubble market than has traditionally lacked transparency. According to the Consumer Price Index, the cost of textbooks has risen 812 percent in the past 35 years, over three times the average price increase of goods and services overall.

As Frank and Halpern note in their blog, the industry is also oligarchical—dominated by five publishers that can afford to keep prices high by suppressing competition. These publishers also frequently release new editions of their textbooks, making the old ones outdated and forcing students to buy updated versions. In other words, they are not looking out for students’ best interests.

Fortunately, guys like Frank and Halpern sticking up for students’ wallets. Companies featured on their plug-in or website pay them a 6 percent commission fee for every book sold, but the founders’ ambition goes beyond making a profit.

“The immediate goal is to help students save money,” Frank says. “But more generally I hope it shines a light on the bookstores’ inflated prices and their position of power, adding transparency to the whole ecosystem.”

Which is probably why Follett, the company that services over 1,700 college bookstores around the country, is already threatening legal action. Follett recently emailed Frank and Halpern requesting that the extension be taken down.

But the two don’t believe that Follett has any legal basis to fight them, so they decided to rebuild and rebrand the tool as Occupy the Bookstore, just in time for the spring semester. “We’re confident we are completely in the right,” Frank says. “But it’s definitely scary because Follett is a multibillion-dollar company, and we’re just a bootstrap startup with three guys and small office.”
