Other than play-asia.com, are there any other trusted online stores that have Nintendo DS games in store?

thanks for all the suggestions, guys. that time when I made this thread I was looking for a particular game, Megaman Zero Collection, but in the end I got it from play-asia.com. but anyways thanks for all the suggestions.

another question tho, does anyone know if there are stores that sell the cases that store NDS games, especially the ones that has a gba slot? Looking for some.
