Cross Recommendors dont seem applicable because this dataset doesn't
represent different actions by a user,it just contains transaction
history.(ie.customer id,item id,shipping location,sales amount of that
item,item category etc)

Maybe location,sales per item(similarity might lead to knowledge of people
who share same purchasing patterns) etc.
