Restock Tuesday was in full swing following one of the busiest shopping weekends of the year. Stores, big and small, are restocking shelves for the next round of shoppers. “This is one of the biggest days for Liquidation.com all year long,” said Mitch Robinson, operations manager for Liquidation.com. The company is an online marketplace for returned and overstocked merchandise. They boast lower prices than regular retailers and appeal to smaller retail outlets, antique stores, and flea market sellers, looking to buy bulk to stock their shelves with everything from clothing to computers.
