Walmart is one of the foremost in screening item purchases per state. These are a few notable mentions:
While Michigan residents are purchasing Life jackets, Minnesotans are buying Folding chairs -- so they can relax while watching their Upper Michigan neighbors bobbing about in Lake Superior.
New Jersey purchases lists Dumbbells; this nomenclature isn't made clear -- the item or the purchasers?
Tennessee has an abundance of Traffic Safety Cone purchases. I should ask my cousins down there why they're so into highway dunce caps...
Forgive the dark humor in this. The main purchase in Texas has been Wedding Invitations. I believe this trend has been quite interrupted. Foz has posted numerous warnings about marriage -- and Harvey's marriage to Texas has been a disaster; in the current weather development, we're hoping Texas rebounds in the divorce without embracing another.
