Looking for Test Drive Promo, especially for Subaru

I read on this subreddit, 8 months ago there was a post about getting gift card when doing Subaru test drive. I tried to replicate but so far has not found the pop-up window (I tried Google Chrome's Ingcognito and Microsoft Edge's InPrivate mode).

I am looking for a SUV and will appreciate if I can get some thing along my test drive and car research journey.
