Olevia is not at Costco and is still very inexpensive
I know Costco accepts anything via their return policy, Costco sells Vizio not Olevia, how did you return the Olevia to Costco? Olevias, they look great and are very inexpensive.
I bought a Sharp, 52" 1080p LCD set, it is very nice, but I would have had almost just as good of a set for a third less. Even Consumer Reports has great reviews on Olevias for their value, and has them as a "Best Buy." The company that makes them actually reports that they have relatively low return frequency on warranties, much less than regularly anticipated. Read the thread, more people are satisfied and it looks like you are the only one who is not, are you sure it was an Olevia that you bought from Costco?
