Written - How do I get sales data of a product?

I looked into Mintel Reports they do market analysis and market studies for some oral hygiene sales reports. I thought if I had data of their sales within the last 5 years in comparison to a gender specific product in the same category I could find whether or not using gender is actually a useful sales technique.
However, looking on the website to access these forms they are £1,000 and over. I have emailed Mintel to ask if they have any information free of charge.

This is the kind of report I need but it is £300
