Yep they tend to try to help by grouping things by task as opposed to strict alpha order. My link gives the picture, title & their "SKU" number which the desk will have no problem helping find the item if it's in stock - their website is usually pretty accurate with a store's stock level - or they can order it in (possibly at a charge unless you break a ££ spend level - usually not much)
Good advice, it's really runny..
