I won't be taking advantage of it but the Audubon center in Bernardsville NJ is having their native plant sale this year much to my surprise. This year you need to order online and pick up the plants at the specified day/time on the weekend of June 6. They have some plants not as easy to find elsewhere and in the past I've been satisfied with the prices. These are mostly plants geared to supporting wildlife including pollinators and plants which won't harm wild areas by spreading there and crowding out native species.

Here is the link to their order form in case you're interested:
