Walmart offers the Delray Plants 10" Cateracterum Palm for $28.50. (Home Depot sells it for the same price.) Opt for free Site-to-Store pickup to dodge the $5.99 shipping charge. That's $5 off list, tied with our mention from a week ago, and the lowest price we could find. It comes in a 10" pot and is purported to help purify the air.

Note that it's not for sale in California, Arizona, Alaska, or Hawaii.
