My husband and I received 6 Wal-Mart Visa credit cards $50 each for Christmas. We went to the Wal-Mart Super Center in Round Rock, Texas to purchase a $600 laptop but we were unable to use our Wal-Mart Visa gift cards to make the purchase. The register locked up during the transaction and the mgr was called to abort the transaction. We not only had to purchase the laptop on another form of credit BUT had to hassle with Wal-Mart from 10:30 am until 4:30 am to make sure the funds were put back on the cards (normal wait time is 10 days). Therefore, Wal-Mart was unable to process our transaction using the Wal-Mart Visa credit cards. read full review »
