Image Anime has a ton of SHFs, including Tamashii Web exclusives. However, they sell for rape-prices. Still, they also have a fair selection of older SHFs, so they're worth a look.
Chinatown has a bunch of stores with a variety of toku toys, from SHFs to henshin gear. The prices and selection vary every time.
Kinokuniya is a Japanese bookstore, but they also have some candy toys.
