Easy to navigate the website Package delivery in a very timely manner, well packed Items seemed to be excellent quality but they won't be truly tested until Christmas as they all gifts The free gift of the yellow, plastic, sticky thing(?) is tacky...suggest you add an item of real value or don't include it at all - detracts from the overall quality...
