I wouldn't go by anything on Wiki. Most of it (if not all) is information from internet users, I believe. As in, no one's full-time job is research. We weren't even allowed to say "Wiki" in college.

Yes, they have a new house and take fun trips, but Kate still gripes about coupons, talks about economizing, etc. We're similar in that respect. We have nice things, a couple of cars, take our Disney trip(s), take our NYC trip, have shopping weekends, etc., but I still look for bargains, love freebies, sell at our consignment sale, cruise the Budget Board and clip coupons. I do those things so we can enjoy the luxe perks without a thought. Being relatable and well-off aren't mutually exclusive.
