Sharing the ISO image is exactly what I’ve seen done in years past, and I think I’ve loaded a shared ISO at least once myself. I think there have also been folks who’ve identified the data file on the disc that determines exactly what deals are offered and shared that separately with notes on replacing it in your own ISO.
Your deluxe deal is obviously hard to beat, though I find links for $24.95 premium still available (and that’s what I used). If you care to share, this expired thread from a partly competing site shows how someone did it last year and the discussion around it:
Like I mentioned, I’m already set for this year, but maybe other posters here could let you know if there’s interest in your Deluxe offer.
