Ahh, I remember something similar.

I remember there was a "secret fairy shop", which was a hidden clickable link. And the shop was usually empty, or stocked with low-worth items. But every 1 hour or so it would stock with high-value fairies that can level up the power of your neopet, and these prices were always significantly below market. Kind of reminds me of Rolex :)

I remember reading guides as to how to time the purchase. I'm kind of surprised more enterprising users didn't write bots for this, as I always remember it being possible at human reaction time to actually pick something up, which I imagine would have been impossible if bots came along.
