Costcoâs business model is called a subscription business model â customers who want to shop at the store must buy a membership (currently $55 in the U.S.) with the promise of lower prices to make up for the initial upfront cost.
The more months payed for upfront, the cheaper the cost per month. E-liquid subscriptions range in price form $29.99 paid monthly, $86.97 paid every three months or $167.94 paid every six months. All three plans include shipping in the price.
