I used bigwords.com to find great deals on textbooks for 4 semesters of college without a hitch. However, this semester I only had to order 3 books. My calc book never came and I had to spend time getting a refund from the ebay store that bigwords showed me and spend and extra $100 to get the book at the campus bookstore. One instance isn't enough to make me stop using the service. However, my communications book didn't come either now. I ordered it three weeks ago with expedited shipping. TWO instances in one order is enough for me to stop using the service. I am done with bigwords.com. I would caution the rest of you about using it as well.
Picture unrelated but it makes me feel better.
