Marginal Revolution on Cross-border shopping

I'm kinda bitter I didn't find this story first, but instead I'm just stealing it. From Marginal Revolution.

Canadian shoppers taking advantage of the parity between the U.S. and Canadian dollars are leaving behind more than cash when the head home.

They're leaving behind their old clothes.

Some Canadian shoppers wear their new clothes home to avoid paying a duty when they cross back into Canada [TC: do we reallly need the link behind that word?]. The old clothes get left behind in parking lots, dressing rooms and restrooms at malls and shopping plazas in the Buffalo-Niagara Falls region.

At the Fashion Outlets mall just outside the city of Niagara Falls, managers have placed collection bins near the exits where Canadians customers can deposit their unwanted items.

Here is the story. Thanks to Bill Griffiths for the pointer.
