"Some come in every day and others come in once a week. Some of them want to see all the new releases but the bulk of our customers come in for the weekly deals.
"The family section is one of the most popular and during the school holidays a lot of the family DVDs will be out. The box-sets are also quite popular, especially Game of Thrones.
"Our busiest days are the ones when you least expect people would want to come out. When it's raining, we are busy."
The store has more than 16,000 movies in its database and new releases are being added all the time. While there were still games available for hire, Mrs Spence said they had stopped buying new ones.
"There are lots of games online now and they are very dear to buy at $80 to $100 each - and a lot of times we don't get them back."
In the heyday of video rentals, Whanganui had four main rental stores, Video Ezy, Blockbuster and two United Video outlets. There were also numerous smaller outlets, often part of other shops.
Mrs Spence doesn't know what the future holds for her family's store but while there's still enough interest to make it viable they will keep going.
"We are still getting sign-ups. People moving into town are surprised there's a store still around."
Video Ezy began with one rental store in New Zealand and built up to a $125 million business with 170 stores as the industry became bigger than the box office. Now there are just 17 stores left in the Video Ezy chain. The demise of the video store is blamed on internet streaming, illegal downloading and changing habits, such as time spent on social media.
