I added an item to the shopping basket (eco15p air con unit £499) and then rang the supplier regarding availability/delivery. After I made the call and was given the info I then went back to the webpage within a matter of no longer than 10 mins (had to see to my little girl) only to discover they had then increased the price to £539... I have emailed them to show my disgust, but as yet have had NO reply! I have now found another supplier that has stock of said item for original price. This site has taken advantage of enquiry and current weather conditions. I'm just glad I noticed before placing order!
