If you are looking for ingredients for asian cooking I definitely recommend taking a trip to lotus! They have a wide selection of items and even if your giant eagle (or whatever store) has the items too, the prices at lotus are probably better. Of course that depends, but for me here is an example:
Identical can of lychees
Giant eagle: ~$4.45
Lotus:~$2.20
Crazy!
It's also fun to browse and just try something new.
If you need curries, tapioca pearls, tofu, durian, galanga, dried mushrooms... you'll find it all here.
Just a couple random examples.
They have sweets and they have housewares like certain cups and dishes, chop sticks, etc.
