A fun promo game for you - simply choose & post an item from your shop which matches one of the 2 themes suggested by the person above you, then add a choice of 'This' or 'That' for the next player to choose from.
So if somebody above me had posted the options 'Christmas card' or 'Sunshine yellow', my choice would be Christmas Card:
