My grandmother has had a Chi for the past 3 years and bought a new flat iron not too long ago. (She gave the Chi to my household.)
I have used the Chi about 10+ times, I recently got a 'titanium' flat iron from TJ Maxx. (only used it once, can't really talk much about it yet.) My problem with the Chi is that, the one that my grandmother had, there was one temperature and you could not lower the temp if you wanted to. (If you decide to get a Chi, try to get one with adjustable temp.) As far as the "foil" falling off, my grandmother's did not do that. If you don't want to buy an expensive flat iron, such as Chi, I would recommend getting a Hot & Silky flat iron from Sally Beauty Supply Store. I have owned one of these for 4+ years and just recently had a problem of the plate falling off when I dropped it (1 of at least 10 drops). These are not as expensive as the Chi, and have adjustable temperatures. I don't know what type of hair your daughter has, but I have 4A-4B type hair, and prefer the Hot & Silky over the Chi any day.
As for coupons, Ulta always has some type of coupons available. As PP said, I hold out they should have some more good coupons coming soon since the Holidays are coming up.
