These are indeed Dollar Store wire baskets. This was a best kept secret of mine since I never see more than a few baskets in any given store. I told my oldest son about them and now we scramble for them when a supply arrives. They're cheap and they last quite a few seasons. I plant in them as much as I use them for covering.

Glad you mentioned squirrels. I didn't include them in my post, though they are the biggest problem of all. Had a couple of cats here that did a good job of keeping them at bay, but now we're down to one. She still does a pretty good job, but it's hard for her to keep up without snakes to help her.
