So you found the perfect bottle for your product at the right price with no lead time! What you didn't realize is that the bottles are stocked in New Jersey and they need to get to Portland. You were so excited to find the bottle you wanted in stock with no lead time but the transit time is looking like 5-7 business days. Did I mention your shipping 4 pallets of glass? That can add anywhere from $1500-$2000 depending on the day and the carrier. This is often the last thing decision makers think about when it comes time to place an order.
Of course, the case is not always as extreme. Plastic is a lot lighter and therefore cheaper to ship. Some carriers, while the distance is great, have preferred lanes and travel them frequently, reducing the cost. This is why it's important to work with several freight company's and brokers and compare rates. If you work with a packaging distributor, they offer products from a large network of manufacturers located throughout the US, Canada and other countries and are able to offer the product that meets many of your needs while keeping these pesky freight costs down.
