I find your website very annoying. I would appear that if you want multiples of any single ink colour you must select the quantity on that item then go to checkout. If you then want more colours you have to apparently go back and select the next item then go to checkout again. If it is possible to select all items at once with one trip to checkout I'm afraid it was not obvious to me. I gave up and phoned in the order which I think has also gone wrong. I ordered two light cyan, two light magenta and one yellow for an Epson PX730. Your order acknowledgement does not show all the items ordered. I came very close to switching suppliers as a result of this experience. a Cook
