As we continue to execute our growth strategy and focus on our core products, we believe that we can, over time, continue to improve our operating margins and expense structure. In addition, we have implemented plans focused on cost containment, customer profitability, product and pricing controls that we believe will improve our gross margin and reduce our losses.
We expect that our advertising and promotion expense will continue to decrease as we focus on reducing our expenses and shifting our promotional costs, in part, from general branding and product awareness to acquiring customers and driving sales from existing customers. We expect that our discounts and allowances will continue to decrease, both overall and as a percentage of revenue, as we further reduce certain discretionary promotional activity that does not result in a commensurate increase in revenues. In addition, we expect our gross margin to increase in future periods due to a decrease in protein prices which began in the fourth quarter of 2019, although protein prices will continue to fluctuate.
