In Midtown Manhattan you can find The Food Emporium, or D'agostino almost on every other block, BUT they are expensive. There is a Target up in Harlem around 125th St and the FDR Drive I think....you will have to take the bus uptown on First Ave or Second Ave to get there. There are also Pathmark Supermarkets....take the #1 train to 207th St., and it is right down the block. My advice is Google the following stores.....Pathmark, The Food Emporium, if you go to Brooklyn there are Waldbaums Supermarkets also, by the way, all of these are owned and operated by the A&P which is in the suburbs of NY and NJ. All of these stores usually have great sales on Tide or Wisk etc. Good Luck
