Ok, for the shoes, if your size is US 11-13, normally you can catch them at World of Sports at 50% discount. They clear those odd sizes quite frequently. Although will normally be at least one model old.
Of Osprey bagpacks, go to any Sports Connection. The one at Plaza Singapura is quite big and complete in the range. One thing to note. There are normally 2 price tags. The 'Original' and the 'special' price. However, normally, they will charge you another 20% off the special price. Ask the staff for it. Unless you REALLY HAVE WHITE SKINS. But, be persistant. Cause that is the normal street price here. (For sports connection)
Basically Deuter's quality dropped lately. Especially the internal linings. They tend to flake a lot now. I would advise you for Osprey. Although, the pricing is still a little on the high side.
