Shopping at Kohl's is like playing the lottery

I don't shop at Kohl's very often, mainly because it's not too regularly that I'm buying clothes or general items for around the home. (I work from home... how often is it that I actually *need* to wear clothes anyway?) I do have a Kohl's card, however, because around Christmas time it came in handy to get the extra 15% off you're granted with when you get a new card with them.

If you keep up with Kohl's at all, you'll know that right now they have a "sale" of sorts (though, doesn't Kohl's always have a sale anyway?), where if you pay via your Kohl's card, you can save "30, 20 or 15%". I've never quite understood what they meant by that until yesterday.

My family and I were out and about and ended up stopping by and bought some stuff. The whole time I'm of course preaching to them how we could have bought the stuff online and saved 30% and gotten free shipping by using my Kohl's card. Plus, save gas to boot. We notice the signs around the store touting this "30, 20 or 15%" savings, and since I'm accustomed to seeing that on their website when they offer 30% off, I thought "cool... we'll still be able to get 30% off since I've got my card on me." Needless to say, it wasn't quite that simple. When we got to the checkout, the lady at the register asked if we had any coupons. We said no, but were going to use the Kohl's card so that should get us 30% off. However, she had other plans for us.

The lady stated that some customers received coupons in the mail (I have no clue if I had or not), but for those that hadn't, they had scratch-off cards that you could use to see which of the 3 discounts you could get that day.... Seriously?..... We scratched it off, and as I figured, it only said 15%, so she quickly began entering that into her register. We paused and were like "we could have gone online and bought this same stuff and gotten 30% off, what's going on?" She had a blank look on her face as if to deny that this was the truth as she continued to ring up our merchandise. We looked at one another puzzled, not really being able to believe what was going on.

We ended up just going on with the 15% off so as to not cause a scene and hold everyone up, but I still feel very abused leaving that store. Don't throw 30% off in my face if you're not going to give it to me. Why would I go into the store and only get half the discount that's possible if I were to order online? The woman was totally unwilling to offer any help or let us have another go at the discount lottery, and I have a firm belief that all of those scratch-off cards said 15%.
The receipt had a survey request on it, so I whipped out my iPhone in the car to fill it out, hoping there'd be an open text field to leave a comment so I could at least let the company know the sheer stupidity of this, but alas there was none to be found. Sigh... maybe I should have started throwing a fit until they offered me even more than 30% off for my troubles. I'm just not that kind of consumer. I'll remain behind my computer to make my purchases, thank you very much.
