REGEX Query in Google Sheets

Having a bit of a headache with a scraping scenario I'm trying in Google Sheets.

In a nutshell, we want to use Google Sheets with ImportXML to create scraped feed from clients' websites pulling product details.

Here is a link to the smaller version of the doc. https://docs.google.com/a/sprt.co.za/spreadsheets/d/1dSbglYniWa_cijb6yDty576j33CTk9Cf8J38a3VXHSU/edit?usp=sharing

Currently this specific client only has the Item Price, etc details in a text area in the code. So when I use =ImportXml($C$2, "//textarea") it gives me the entire text area across two cells. From these cells, actually only the second one I need to pull out details but I am pretty stuck on the Regex on a piece if data this big.

" { ""id"": ""061013AACI9"", ""productId"": ""061013AACI9"", ""name"": ""VANS MEN'S 
PERFORATED LEATHER ERA"", ""price"": ""R 799.00"", ""oldPrice"": """", ""brand"": 
""Vans"", ""brandURL"": ""/plp/vans/_/N-1z140je"", ""defaultImages"": [ ],

I need to pull out the R 799.00 value from that mess. So if anyone is willing to help out. Because frankly my talent and skill has run it's course in trying to navigate that with RegEx.
