With an even split between business to business and business to customer sales.

Cape Coffee Beans get most of their sales from Google Adwords, using display Ads They have a return of R6-10 for every R1 spent. 

Facebook and Instagram have offered R1 to R1 return in sales in the past for Cape Coffee Beans, they have a particularly niche market and having social media pages provides credibility but paid advertising is not as successful for them. 

Back in stock reminds customers about items they have on back orders and this mailing tool drives sales well. On Mailchimp with weekly mailers they have a 10% click through rate! 

On a different note, Cape Coffee Beans has spent time on Price Check and other pricing websites and had some success but their
coffee is high end and not marketing to an audience looking for good deals.
