Display MSRP prices to your customers
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 it’s a good idea to buy from you.
On your product edit screens you’ll now see an extra field in with the normal pricing information, labelled MSRP. You can enter the MSRP here and it will be shown on the front end to your customers. If you’re 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.
