Target (NYSE:TGT) has had a rough start to 2013. Sales and earnings came in lower than the company expected this past quarter. And the company expects the rest of the year to be soft as well. However, the retailer has notched good results with its loyalty-card program, which bodes well for future sales gains.

In the following video, Fool contributor Demitrios Kalogeropoulos argues that the loyalty program could work just as well for Target as it is has for retailers such as Amazon.com (NASDAQ:AMZN) and Costco (NASDAQ:COST), which have pulled huge revenue gains from their successful membership services.
