I order at kohls.com all the time and never pay for shipping. I can usually find a free shipping code somewhere on line. Returns at the store are simple - love Kohls for this. They never question any returns, there are no time limits, and if you use your kohls charge, they don't even need the receipt. Unfortunately, not the norm for returns in many stores nowadays.
Kohls rocks! They are very good about everything! I just returned an entire $150 order because I reordered it a day later to get everything cheaper lol
