I'm finding that often, the search presents one price for a product but when I click on the product, that price isn't showing but something else. Example - search for Gold Blend and Nescafe Gold Blend 200g Shows as £5.50. Click on it and the best price is £5.99. Add to that the fact that this is an Ebay price which excludes postage the best price is actually £6.70. There is a mismatch in your data somewhere.
