Canning jars in (northern) Queens?
Try Queens Garden center in Whitestone off the Whitestone expressway and Garden World on Francis Louis and 48th. It's a seasonal item though. They usually have them when the tomato seasons begins. I've bought the Mason jars at Queens Garden center before. They have produce in the summers from local farms.
I still see them at Priced Rite on Roosevelt and 64th in Woodside.
The best selection I've seen is at Gracious Home (Manhattan though).
If you're don't need a particular style (e.g. wide mouth for stacking), I've seen the more modern styles at Target.
Michael's on Northern Blvd in Woodside usually has them as well, though it's usually the 1 quart narrow mouth only.
Acehardware.com lists them as well with free delivery to your local brick & mortar location.
