I got a letter from this company stating that I needed to buy my bedding from them since the beds at Portland State University are custom sized, and any standard sized sheets I purchase from other companies won't fit the beds. The letter also gave falsified statistics, said that they *were* the official PSU store, had a return address from PSU, and was titled to my parents rather than me. Turns out all the information was falsified, as the official PSU website shows the bed sizes in each of the buildings. It was also explained to me that they used a legal loophole that forced PSU to release the information for all of it's incoming students in order to get our parent's addresses. Do not trust them!
