Indicate your backup choice or substitute for low-stock items from your cart.
Stay above your distributor's order minimum and make sure your bar is stocked by choosing a substitute for products that may be low-stock or highly requested.
Before you submit your cart, scroll to the distributor carrying that important item. On the upper right of that distributor's section, you should see an option for "Add note or backup." From here, you can leave your sales reps a note about any substitutions you would like to request in the event one or more of the products in your cart are out of stock.
