It is one the busiest weekends for retailers across Wales as thousands of shoppers rush to pick up last minute gifts for Christmas.
Chris Parry, a senior lecturer in Banking and Finance at the Cardiff School of Management, said it will be "the best year (for retailers) for three or four years".
"Smaller businesses have had two of three years where they've struggled tremendously.
"This Christmas is going to help them. It's going to save many of them from going out of business."
