I found a great deal on Amazon for travel backpacks.
The purple travel backpack is on sale for $42.99, but you'll get a better deal when you use the promo code 50J8MAQC. You'll score 50% off and pay just $21.49.
There are a few other colors on sale, and the same promo code will apply to each one; just be sure to shop from the sale page that I linked above.
Take a look at more backpack deals and score more savings with these Amazon promo code deals.
