I was making my first purchases with the in-game gold auction house and had difficulty finding items I wanted in my level range that had buyouts in the price range I wanted. On the bright side, just about any item I could dream up was there.
The disheartening thing is, the majority (seems like 75%) of auctions don't even have buyout prices.
Even when sorting on buyout prices, I had to sift through 45+ pages of N/A's to get to the lower end of the buyout ranges.
Do people just not know that customers want instant gratification and don't want to wait hours or days to get their item?
