Prices are based on supply and demand, but also depend on suppliers and the availability of goods. As prices can fluctuate on a daily basis, we provide you with a 'Price evolution' tool to give you a better idea of the current trend. In addition, by adding an item to your wish list, you will be automatically notified by e-mail of any price reductions. At the time of writing, we seem to be able to obtain (and therefore offer) the strip alone at a more attractive price than the hard bundle pair.
