To determine shipping costs without visiting the post office, a scale and measuring tape are essential for weighing and measuring packages. The USPS website offers a postage calculator that requires input of the package's size and weight for accurate cost estimation. Additionally, using flat-rate envelopes and boxes from the post office allows for shipping costs to remain the same regardless of how full the package is. For those without a scale, a visit to the post office may be necessary to weigh packages.
can someone please tell me how you determine shipping cost without going to the post office? i see all you lovely cheffers selling things but how do you determine cost?
You need a scale and a measuring tape. The post office website (http://www.usps.com) has a postage calculator on it, but you need to enter the package size and weight. You can also get flat-rate envelopes and boxes from the post office. Those packages can be filled as full as possible and the postage won't change.
