Answers to this question will obviously vary. Some students may prefer Wal-Mart's in-store pickup service while others will value Amazon's home delivery based on time and convenience. Some students may choose one merchant over the other based strictly on prices - it's a toss-up as to which one has the lower price though. Product and service availability may rise to the top for some students - again, it could be a toss-up as to which merchant has more and better offerings. For others, it may depend on the situation as to which one they prefer more.
