I'm guessing that brand name items (KitchenAid, Dyson, Carters, etc) are the same no matter where they're sold, or are you saying they get seconds.
They ARE very overpriced. Often times, their sale price is the original price somewhere else. For example, I bought my little Keurig there, "on sale" for $99.99, which is what it generally sold for regular price elsewhere. I could have gotten it at Bed Bath and Beyond for another 20% off. However, I had a 30% off code, purchased other items I wanted (also for a reasonable price "on sale" plus the 30% off) and got $20 in Kohls cash, which I later used on something I already had in mind that cost $20.
What really irks me about USING the Kohls cash and a code is that they take the Kohls cash off the top, then give the % off, rather than the other way around. Seems to me that the Kohls cash should be used as payment when the final price is determined AFTER the coupon % off.
Having said that, I agree with others about knowing prices. I just got some awesome Carters clothes for my granddaughter starting at $3 each, and I did it without leaving my home (never pay shipping).
