You are selling your organic fertilizer products through two different channels: your website, and garden supply stores. your cost per bag of fertilizer is $2. you sell the bags for $10/each on your website but you sell them for $5/each to garden stores so the stores can make a profit. next year you expect to sell a total $10mm worth of fertilizer, of which 20% will be through your website and 80% through the garden stores. what will be your gross margin on total sales next year?
