I've seen em in a couple Walmart locations (Barrhaven, South Keys). At both stores, the succulents were around the produce/bread section for some reason? beside the bouquets of flowers. 

disclaimer, this was a few weeks ago, I'm not sure if they still have succulents at the same place.

Last summer I bought a bunch of succulents at Walmart for $3 and $4 and filled a planter outdoors - they grew like crazy but didn’t survive the winter in the house - this year I bought a planter twice as large because it worked great - but can’t find the succulents! Has anyone seen succulents at Walmart this year?
