Fresh Milk? That last longer than a couple of day (Lima)

I love my lattes. I love a nice latte first thing in the morning, but I keep waking to discover the milk I had bought a a couple of days, sometimes only one previous is gone bad. I have tried different varieties. I have tried putting it in plastic, and glass containers in my fridge, but it does not last. I am used to milk in Canada being sold in 2 litre cartons that stay in the fridge for a week or more. The bags of milk here have a date on them for months down the road, ie. June Protected content must signify how long the ink on the bag will stay, not the contents. :P Is there a solution> How can I get fresh homogenized milk that will stay in my fridge between trips to Wongs?
