I use these gels whilst running long distance and usually pay 99p each (they're not much cheaper when buying a box of 24!) so I was surprised to see them at my local ASDA (Ashton-Under-Lyne) for 64p each. Got myself 10 and will be going back for more!
These are available online too!
DIY: Mix sugar & water! [less then 1p!]
