Amazon still has 20+ pages of items and auctions on eBay say this;
“NEW LISTING Rebel Confederate Flag 3 x 5 ft New banner with brass grommets
DUE TO HIGH DEMAND,ALL FLAGS WILL BE SHIPPED JULY 2ND”
Looks like they pulled down the flags some time in the past hour. Related novelties are still up (beach towels, etc.)
It will take some time to push the policy down.
