This is really the only place to go if you're looking for a Longhorn-themed gift. You will find anything and everything under the sun with the Longhorn spirit on it. Their bumper stickers and T-shirts section have a great selection. They don't have many great deals but it's likely that you won't find those in many places. Longhorn items are always in style in this town.
If you're a student, you will find decent prices for the books that you sell back. There used to be more competition on this end, but the Co-Op has recently taken over that sector. Still, they haven't gone completely off the end and still give pretty good returns.
