I think you have to go back and see if there was barbed wire around the bat, showrunner Scott M. Gimple coyly told The Hollywood Reporter at Comic-Con when asked if Negan was on tap for season five.
What is a trade discount? A trade discount is a reduction to the published price of a product. For example, a high-volume wholesaler might be entitled to a 40% trade discount, while a medium-volume wholesaler is given a 30% trade discount. A retail customer will receive no trade discount and will have to pay the published or list price. The use of trade discounts allows for having just one published price for each product. The sale and purchase will be recorded at the amount after the trade discount is subtracted.
Trade refers to buying and selling of goods and services for money or money's worth. It involves transfer or exchange of goods and services for money or money's worth. The manufacturers or producer produces the goods, then moves on to the wholesaler, then to retailer and finally to the ultimate consumer.
