Most event planners, businesses and even shop owners buy large packs of wholesale plastic tumblers in bulk. It makes economical sense to order in bulk as most manufacturers offer discounts on bulk purchases. Wholesale tumblers can be single-wall or double-wall, with or without handles, differing by type and size. Customization like logos or color changes is quite common for bulk purchases. This is beneficial for companies that want to use the tumblers as marketing tools for advertising purposes like gyms that give new members tumblers. Retailers also benefit from the bulk purchase option as it allows them to stock popular designs at competitive low prices.
