Kmart

I went to the store on the first day of a several day mailer promo to purchase bottled water. I picked up a case from the only display and at check-out wsa told they had none and my case was not the promo item even though it matched the ad.
No rain check was allowed.

Such will teach me to either call ahead for stock or to avoid the store altogether. I had hoped the association with Sears would raise the otherwise poor business practices / public relations common to kmart. Such is not the case.
