There are rarely dicsounts on the higher end ones like Pandora, Chamilia & Troll - sometimes they have a bead promo - like buy 3 or 4 beads get the bracelet for free. You will get a much better deal on the one at Kohls, just be forewarned that not all the beads from the different brands are interchangeable with each other. I have the Pandora bracelet, but have bought 4 beads so far from Kohls that do not fit. I've heard the same with the other brands as well.
Kohls does have great sales on their beads though - they're often 60% off plus whatever % off coupon you have for Kohls. If she really doesn't care what brand it is, I'd go with the Kohls one.
Also be aware that if you do splurge on the Pandora bracelet, if she has even one non-Pandora bead on it & has a problem (other brands beads tend to get stuck or damage the threading) - they won't even look at it for you. The warranty becomes void once you place anything on it non-Pandora.
My favorite beads are actually the cheap-y ones I got in Disney 3 weeks ago - lots of Mickey heads, plain & with rhinestones, Tinkerbelle and others, for $3.95-$5.95 each!
