Description The SMARTEST way to buy, rent or sell textbooks and everything else.

V. 3.0 has barcode scanning, persistent bookbags, and support for comparing prices on every product in the universe, not just textbooks!

BIGWORDS saves about $1,000 per year on textbooks. WE DON’T SELL ANYTHING. We find the cheapest prices to buy or rent by comparing prices at every good online store. With this release, we are bringing the same multi-item price optimization, including coupons and shipping to every product in the universe. Back to School: #1, Top 10 iPhone Apps for Students " and the app are welcome additions to the quest of buying books... you will save money using this app... I really like the app. It’s simple, straightforward and will save you money."

New York Times App of the Week: "...a savings of more than 35 percent over buying online without its search engine."

Chicago Tribune says: "...there are at least a half-dozen Web sites that sell used books in good condition... You can search each of these sites individually, or you can [use], which offers one-stop shopping."

The BIGWORDS Uber-BOT textbook price comparison uses Multi-Item Price Optimization(tm) to maximize promotions and minimize shipping, providing the lowest total cost for your entire textbook order.

Buy, rent, or sell textbooks: New, used, rentals, eBooks - All considered to save you the most money.

...And that’s not all. It’s not exactly Snuggie, but it’ll give you the same warm fuzzy feeling when you realize how well you’re stickin’ it to the bookstore man. If we find books from sellers with low feedback scores, we’ll strip them out for you! Book looks like it’s been run over by a truck? Not a problem! We’ll ignore it. What’s that? You don’t care if it was run over by a truck and fell into a sewer? We’ll show you the very dirt-cheapest textbooks. Nobody, and I mean nobody, does textbooks like this. We slice ‘em, we dice ‘em, we find the cheapest copies of the right textbooks so YOU don’t have to spend your hard earned cash OR spend hours scouring the Internet for deals. This thing cleans up textbook prices like a Sham Wow does grape juice.

Voted most important app by all of us who built it, we believe you will be as overjoyed as we were when it started working. In fact, we’re so sure you’ll be completely satisfied that we’re giving it away FREE! Not a limited time offer. This thing is free and it’s going to stay free, because we love and respect you, student kind.

Multi-Item Price Optimization(tm) is a process which calculates the total price for every permutation (combination) of books and stores, taking into consideration shipping and promotions for each combination, thereby finding the lowest total price for your entire order. It’s why we save students $225 on average multi-item orders.

Crashing app

This app frequently crashes, maybe it is just because I'm trying to sell textbooks but that has even more issues that to buy textbooks. The website is great. The app is a fantastic concept but it needs more work. Love the website

Can't change things

Crashes every time I try to change something in options. Great concept, love the website version, but app is difficult to use

Great Concept for iPad but needs work

The app resets each time you exit so it will not allow you to build a book list.
For example, I have a PDF open with my 7 book titles and I copy and paste each ISBN to BIGWORDS, but each time I switch apps, the saved book is gone. This makes it impossible to build a book list without either printing the list or viewing it on another device...
