Proposition
-----------
Vinyl is making a comeback, sales have grown every year in the UK for the last 9 years.  
50% YoY growth in 2015 UK.  Turntables were the most popular audio item sold on 
Amazon during the run up to Christmas 2015.

People now  discover music through digital services, the common way to bookmark this 
music is with playlists.  We make it easy to go from playlist to physical vinyl.
Shipping can form a large percentage of the total price for vinyl (typically 10-50%)
so we help to find sellers who can combine shipping for multiple items.
