(Portland, OR)  --  A customer of Safeway is suing the store over a one-percent surcharge on items in Portland.  The complaint was filed in Multnomah County Circuit Court yesterday.  It alleges Safeway was practicing unlawful trade and unjust enrichment by charging a 3-cent surcharge on a bottle of wine advertised for 3 dollars and 33 cents.  This is the second Portland business to face a suit for passing on a surcharge to customers in response to a new city tax on some retail items.
