I have been going to the new warehouse-size Asian supermarket in Hempstead after a poster here alerted me to its existence. It is a major addition to food procurement (procuring?) in Nassau County.
My shopping cart last time I was there: Chinese pork buns, fresh and dried Japanese noodles, dried shrimp, Asian basil, green papaya, quail eggs (half the price of Balduccis!), long green beans, Japanese seaweed, frozen Vietnamese spring rolls (don't have high hopes for these but thought I'd try!), a frozen whole durian, several unripe coconuts shaved and shaped to insert a straw and drink the sweet coconut water (a bit more than $1 each), Vietnamese fish sauce.
Friendly, helpful management. When I chose a fresh durian, the cashier alerted me to a breach in its surface that I had not noticed and a manager ran to get me a better one. Fresh durian is prohibitively expensive ($3.99/lb and a durian can be 10 lbs). I wound up putting it back and the manager cheerfully suggested I go with a frozen one (I think $1.79/lb).
Most things are quite cheap (not durian, obviously).
Very interesting and excellently-priced meat case. Rabbit at $2.29/lb, lots of things I have no idea how to use such as black chicken, kimchee chicken feet.
Lots of fresh-looking greens (have not identified them all) and fruits and many of the things I would go to Flushing for, with the exception of prepared foods.
You can also buy many of the things that a regular supermarket carries, i.e. Cheerios, ketchup. I am finding that sometimes it can be a one-stop place for me.
With this market, Fairway in Plainview (I know, it's far from perfect but it's better than what we had), and Patel Brothers in Hicksville for Indian ingredients the food picture for Nassau county cooks has brightened considerably.
