Good one out towards Hazel Grove, on Heaton Moore. Because of Stepping Hill Hospital there's a fair few Filipinas in the area. Can't remember what it's called but wifey still orders from there.
Some of the Chinese supermarkets in China Town have a few shelves with Filipino products. Even if you don't get the exact Filipino brand you are looking for, there are lots of things that Filipinos love eating which you don't tend to find in Sainsbury's. And there is the Oseyo Korean shop on Oxford Road. They have some Filipino brand potato chips and snacks upstairs. Again, lots of non Filipino products like kimchi, spicy fish sausages etc that Filipinos love. Other than those, I think your options are Adastra in Stockport (easy as a pop down the shops for a Stokie) or a place in Burnley which I keep intending to visit. The Korean place, Oseyo, is my wife's favourite.
