Not likely. I know of no New Yorker who would travel to Kearny for a Wal-Mart. Plus, there are stores with similar merchandise at similar prices in NYC...If you have some inside stuff on that actually being Wal-Mart's plan, they're more screwed up than I imagined.
Perhaps they never go into New York.
Unions would be the death of Wal-Mart, and they'd abandon an entire city or region if they had to to avoid them.
Then you don't know many New Yorkers...........
Nearly every New Yorker I know, and I know plenty and am related to plenty, are regular shoppers in New Jersey in order to avoid the NYC sales tax. I don't know if any specifically go because of WalMart, but they do go.
