I saw the list of their memorial day sale a few days ago on a forum that includes their premium component cable and cooler stand for Wii. The cable is still very expensive but the $9.99 (after discount) cooler is a very good deal. It is the pretty much the same as the Brando's cooler but with GameStop's logo on it. The same cooler is selling at $15-$20 elsewhere. I picked up one this morning. It is pretty quite.
Product page at Gamestop.com. More pictures on this site. There are some wrong information in the user comments. I guess they bought a different cooler stand for Wii. First, the blue light can be turn off. It has 3 setting positions: Off/light/light+fan. Second, the fan runs even at standby/Connect24 mode. Third, this model does not have the holder for WiiMote or Nunchuk. It is the same shape as the original stand by with a smaller foot print and is transparent. Fourth, the fan is very quite.
Anyway, $9.99 is perhaps the cheapest cooler stand for Wii if you need one.
