Wow, I had no idea Walmart printed checks! Anyway, from what I can determine, you order the checks online at the Walmart site, then they are shipped directly to you. I don't think you can pick them...
The creater of walmart is named Sam Walton, So I am assuming the Wal comes from his name, and the Mart comes from the fact it is a store.
yes they do
my dad calls it wally world
Walmart has everthing you will ever need.
