Better World Books puts a $3 off promo code at the top of the page for purchases of 4 selected used books, and it works best for shoppers buying a modest haul. The brand also runs category sales on everything from textbooks to individual titles, which can reach much steeper discounts on certain items.
Buying 4 selected used books. Use the featured $3 off code at checkout. It applies to the selected used books only, so check that your chosen titles qualify before you add them to your cart.
Buying textbooks for the semester. Skip the promo code and shop the up to 90% off textbooks sale instead. The textbook markdown applies to selected products only and beats the $3 code on any order where the discount percentage is meaningful. On a $60 textbook, for example, 90% off brings it to $6, a saving of $54 compared to the $3 code alone.
Buying one of the featured discounted titles. The brand currently has several individual books on sale: "Memories Of A Cuban Kitchen" at 75% off, "The Big Book Of Christmas Mysteries" and "Folk Wisdom For A Natural Home" each at 49% off, "Best Martin Hewitt Detective Stories" at 33% off, and "Meet Me At The Lighthouse" at 6% off. These sales apply to those specific titles only. Use the percentage discount, not the $3 code, because the sale markup is higher on every one of these items. On "Memories Of A Cuban Kitchen", if the full price is $20, then 75% off takes it to $5, a saving of $15 far above the $3 promo code.
On any order over $15. You get free standard shipping, so factor that into your total when comparing options. The shipping benefit stacks with the promo code and the category sales, so apply it on top of whichever discount you choose.
First time customer. Better World Books offers a 10% discount when you sign up to the email newsletter before your first order. Use that instead of the $3 code if your total is high enough for the 10% to be worth more than $3. On a $40 order, for example, 10% off saves you $4, which beats the fixed $3. The newsletter signup does not combine with the textbook sale or the individual title markdowns, so choose one. You can apply the newsletter discount to selected used books, though, if you prefer to stack it with a smaller order using the $3 code to no great advantage.
To pick between offers on the same basket, apply each one separately and take whichever leaves you the lower total. The textbook and title sales apply to their specific products only. The $3 code covers selected used books. The free shipping applies to all orders over $15 and stacks with any discount code or sale price.
