Postal and shipping scales are the same. They have interchangeable names.
One of the benefits of having a postage scale is that you can save time and money. If you go directly to the post office, for example, then you would have to pay full retail postage fees.
On the other hand, you can overpay for postage fees if you over- or under-estimate the weight of the product you're planning on sending.
Having postage scales solves all of those problems. The best thing about a digital postal scale is that they don't have to be as expensive, and it will save you from the trouble you will likely get by going to the post office.
Now, what's the best digital shipping scale on the market? It mostly depends on what you need. Some people look for a postal digital scale with a high-quality LCD display, which allows them to calculate weight faster.
Other people go the extra step and go for a digital scale with Bluetooth or USB connections, allowing them to collect and store all the information they need.
SellEton's PS-C30KS series counting scales are perfect for smaller businesses that want a high-quality postage scale. These come with a maximum weight limit of 3kg, 6kg, 15kg, and 30kg.
However, if you want to go a step further, then you can get one of the other listed models on this page, which have a higher maximum capacity.
