Query: Poor Quality

The quality of this backpack is rather poor and comparable to many that are sold at Walmart for $15.00, so I paid twice as much! The bottom fabric is not sturdy enough to take the daily cramming of schoolbooks, and i doubt will last more than 3-4 months. Actually, I did find one backpack at Walmart that did have a pretty sturdy bottom about a year and a half ago for only $15.00; it finally wore out and since it isn't the beginning of the school year, Walmart's stock of backpacks is too limited at this time. That's why I thought I'd try to buy one online. I'll never do that again. Some things should only be bought in person.
