Hello:
I have found that some of the local bigger produce markets will sell you from their stock. You may even find others in your community that need baskets and order together.

I bought some white plastic mini-storage bins at Wal mart 6"x4"x3". They are made like a lattice work and are found in the household/kitchen storage area and cost about 35 cents each in a pack of 4 as I recall. They hold about 1 qt and are washable and durable enough to last for years. I buy bulk rubber bands for squash and cucumbers, and use recycled grocery bags for everything else.
