what i think it means is that consignment stores and thrift stores get single items from consignors/donators. in other words- "one of a kind".
often big thrift stores buy new items in job lots from manufacturers or in the case of a consignment shop some will supplement their used inventory with new socks, tights and barrettes. those are not considered "one of a kind" items as they are bought in bulk quantities and they are placed on the floor and sold as new.
in the article Goodwill says that those products make up only 10% of their kids merch. i took that to mean that they aren't concerned how the law effects the majority of the stuff on their racks -largely manufactured used clothing and toys.
very confusing indeed.
One thing I think everyone can agree on is this law is sooooo confusing. It's like they took a sledgehammer to a fly with this and didn't realize what it would do.
