Hi Hendri,

Thanks for the quick response.
What you suggest is a good idea, but I am lost with how this would
work when say over 1000 customers would buy multiple products. The
product_company_table would need to have duplicate _id's. Although I
know this is allowed, I am unsure how this would react when queried.

Dave.
