What is the fine-grained topic of the following text: Packing to come down there - does anyone know where in Mexico you can buy canned sockeye salmon - it's wild Pacific salmon (sometimes from Alaska),rich in Omega 3 oil, low in mercury - anyway, I need to decide if several tins of it should take up valuable weight and space in my checked luggage, or is it readily available in those big stores in Manzanillo? Only return the topic.
