i have recently found several tall narrow clear snap-top plastic storage containers in charity shops for £1. i can get 3 times the amount of stuff in one cupboard as a result. Very useful for porridge, any loose foodstuffs, coffee, rice, spaghetti ..... a great find
a bit like these Oxo Good Grips Pop Rectangular Food Storage Container 1.6l | Lakeland
Great idea stops these things rattling around when travelling
