Unsure how to ignore a particular line on a website?

[dudenell]

I'm trying to track a website for a purchase of an item that's out of stock (not a gpu or console).

on the webpage is apparently a tracker logging the number of attempts and the changedetection keeps bringing it up:

Original
* window.NREUM||(NREUM={});NREUM.info={"beacon":"bam-cell.nr-data.net","licenseKey":"308175db61","applicationID":"658193364","transactionName":"ZVxbZUFQWBdVW0BdWFwWekRARVkJG0hGW1NHWk1uWl9QCw==","queueTime":0,"applicationTime":51,"atts":"SRtYEwlKSxk=","errorBeacon":"bam-cell.nr-data.net","agent":""}</script>" onload="document.getElementById('Slide7').focus();" >

Change
* window.NREUM||(NREUM={});NREUM.info={"beacon":"bam-cell.nr-data.net","licenseKey":"308175db61","applicationID":"658193364","transactionName":"ZVxbZUFQWBdVW0BdWFwWekRARVkJG0hGW1NHWk1uWl9QCw==","queueTime":0,"applicationTime":52,"atts":"SRtYEwlKSxk=","errorBeacon":"bam-cell.nr-data.net","agent":""}</script>" onload="document.getElementById('Slide7').focus();" >

it appears that this line is the one that's changing: ,"applicationTime":52,"

they also apparently have a random quote generator on the bottom of the page... Any idea how to ingore these changes? Maybe a case sensitive "In stock"?
