maritza68 - with a receipt, you can return something to Kohl's indefinitely. There is absolutely no time limit.
LSoldevila - the next time the lady in CS is a crab, please ask to speak to a manager. As long as you have a receipt, a return is a simple transaction in CS.
maritza68 - since you purchased the pants in early September, they may not have the size you want now or, if they do, they could be yellow ticketed which would mean they would cost you less than you paid back in September to repurchase. With a receipt, you can have your purchase amount returned to your original form of tender or you can ask for a KMRC which is Kohl's Merchandise Return Credit. Either way, you can then go look for the same pants and, if they are still in the store, you will most likely be getting them for less than you paid for them on sale back in early September.
