If a store that runs out of an advertised sale item during a sale period, Connecticut Law requires them to post clear notice in the store that the item is not in stock, and to notify shoppers that they may ask for a rain check.

Consumers should note that rain checks apply when merchandise is offered for sale at a stated price without condition. If a coupon or return of a rebate is required to get the sale, then the merchandise is not technically offered for sale at that lower price, and rain checks are not required to be offered.
