"We are anticipating significant growth this side of Christmas, particularly as we hit some key shopping events such as Black Friday where customers will be able to shop all the deals that matter with free shipping, then the preparation for Christmas Day itself," Wilde said.
"TheMarket Club offering free shipping across the site will be a game-changer for our customers."
Retail analyst Chris Wilkinson said TheMarket's move to operate a subscription model like Amazon was a strategic attempt to snatch a dominant market share in the country's growing e-commerce market.
The Amazon-esque retail model would face some challenges in this market, however, he said.
"There are some deals [to be had], but there are a multiplicity of deals in this space. If you're with Vodafone then you get this [streaming service] for free, or you get something else that you pay a bit extra for, it's quite a complex market. Unless it is something unique [it will be hard to crack]," Wilkinson said.
"The difference with Amazon Prime is it is their own product - it's completely different."
Amazon has its own production division and creates its own video and streaming content that it offers as part of Amazon Prime subscription, which in itself drives millions of memberships. The subscription aims to provide convenience and everything in one place.
"What could be a game-changer for [TheMarket] is if they were able to team with one of the big supermarkets.
"This is one of the steep changes Amazon has done in the United States - owning and working with aspirational food brands ... The Warehouse's work is admirable, but it is really going to rely on a critical mass of consumers to embrace this," he said.
"The offers have to be compelling and the benefits have to 'wow' and customers have to be ordering enough with TheMarket to make this worthwhile."
TheMarket launched in August after 14 months under development, and cost The Warehouse Group $12m to build. The independent subsidiary is similar to popular lifestyle marketplaces ASOS and The Iconic, selling more than 1700 Australasian, British and American brands.
The group is betting on the platform to take a share of New Zealand's growing online e-commerce market.
