Look for Leverage
Consider what customers will pay and what competitors charge when setting prices. If you have many products set at different prices, it is easier to compete by lowering prices on some items in hopes of making up the losses by charging more on other items. These lower-priced items are called loss leaders.
At certain times, you may need to lower prices to improve cash flow or sell merchandise that tends to be purchased at a slower rate. Also, promotional discounts sometimes require a lower price in exchange for increased sales volume. To counter the resulting revenue decrease, try bundling the for-sale product with another item at regular price.
