Could someone tell me where they have found Wonderup the cheapest at? It does not appear to be sold at very many places. Thanks for your help!

No it's not like some of those affilaite products which are sold all over the place. I think everyone here is getting their wonderup from Vortex Health - and it costs less than you might think because they do not charge anything for shipping.

It costs £26.95 a bottle, not sure about delivery charge, its free within the UK lasts about five weeks.
