Display MSRP prices to your customers using this popular extension from WooCommerce from WooThemes
The WooCommerce MSRP plugin allows you to record Manufacturer Suggested Retail Prices / Recommended Retail Prices against your products, and have them displayed on the sales pages. This allows your customers to see why its a good idea to buy from you.
On your product edit screens youll now see an extra field in with the normal pricing information, labeled MSRP. You can enter the MSRP here and it will be shown on the front end to your customers. If you are bulk importing products, then the MSRP can be imported by using meta: _msrp. By default the MSRP will be shown struck-out much like a sale price. You can style these however you want, the whole content is within a div with a class of woocommerce_msrp, and the price itself is within a span with a class of woocommerce_msrp_price.
