OOh. I get a bag of Haribos every time. Mind you, I was a platinum member (before I discovered many other cheaper / faster / better sites). Now using Parkers,
ProbikeKit, ChainReaction.
Not from
Wiggle, but best treat this year was a whole bag of JellyBabies. Opened, unfortunately, and discovered in the pocket of my running belt. I don't run so often now, so wasn't particularly surprised they were a little stale. Consistency somewhere between chipboard and rock. Very nice though.
Less so when I found out it was my wife's belt. Same as mine, but not used since the April 2007 marathon. And she made me replace them.
