Change "PRICE" name and more

Okay here it goes. I tried using the tool kit and found nothing. I've searched the english.php file. I cannot figure out how to do two things. I need to change the word "PRICE" to "MSRP" I also need to add MSRP behind or below the $xx.xx price listing on the product. This site is set up for catalog w/prices and doesn't sell anything. Thus the need for the Suggested retail price.

https://www.bulldawgdistribution.com is the site.

Please hel.

Thanks,

Josh

I do not see the term "Price"
Post a link to the exact page where this is

http://bulldawgdistribution.com/index.php?main_page=index&cPath=23

is the address.
I also attached two snips of what I'm talking about. The 1st one is where PRICE is. The second is the product screen where I need MSRP above the price.

TY,

Josh

define('TABLE_HEADING_PRICE', 'Price'); 

Change to

define('TABLE_HEADING_PRICE', 'MSRP');
