Just a few days after Minneapolis-based Target Corporation said that it had implemented a permanent fix to its coupon glitch, the company was hit with two lawsuits seeking class action against the retailer.

The suits-which were filed separately last week in Los Angeles County Superior Court and U.S. District Court in Birmingham-claim that Target was negligent in shortchanging customers who were using coupons.

Court documents for the case brought by Target customer Karina Olivarria in Los Angeles were not immediately available, but media reports indicate that the case is similar to the one filed by Michelle Norris in Alabama.

According to those court documents, Norris received a credit of $2.39 on two separate visits to two different Target stores when purchasing baby wipes. However, the coupon that she was using indicated that she would be entitled to $2.50 off her purchase price.

Norris said in the suit that she also used a Heinz North America coupon to save $4 off any 10 Weight Watchers products, but the store only deducted $1.80 for the coupon. On that same visit, Norris used a $1 coupon for the purchase of seven Earth's Best Baby Food Jars but she was only credited 57 cents, according to the lawsuit.

“Target often blames 'glitches' in its computer system to account for the companywide behavior but they never correct these 'glitches,'” the suit said.

In late October, Target admitted to a coupon glitch because of which customers were not being reimbursed for the full value of select coupons. At that time, Target called the problem a “complex system issue” and said that it was working on a fix.

At about noon on November 9, Erika Svingen-a Target representative-said that the problem was first brought to the company's attention in August and vowed that it would be permanently fixed by November 15. However, during the afternoon of November 9, Target issued a statement saying that coupon glitch had been resolved for good.

Svingen declined to comment on why the coupon problem had occurred, why it hadn't been addressed sooner, and what was involved in the permanent fix.

Norris' suit seeks class action status and an unspecified amount of money for compensatory and punitive damages and costs incurred for the lawsuit.

Target-which operates a retail segment and a credit-card segment-serves guests at 1,752 stores in 49 states nationwide and at Target.com. It is Minnesota's second-largest public company based on its revenue, which totaled $65.4 billion in its most recently completed fiscal year.
