I thought that if I specified shipping class as “all products in cart” the USPS look-up table app would work correctly. However, it is still giving ridiculously high totals, presumably because it is calculating shipping on each item separately. This is a terrible bug in the woocommerce platform, and I will try to work with them again to fix it. In the meantime, there is a flat-rate shipping option based on average cost of USPS priority mail to your zone, for an average size order. If you only order one item, the calculated price may be less, so I’m including this option.
During the unusual cold spell throughout much of the US, we have received a number of questions about winter shipping. Please rest assured that we will take every precaution to ensure that your plants reach you in good condition. We always check the 10-day weather forecast for our area, your area, and likely transit points in between before shipping plants. If the predicted lows at any point, at any time, are below 26 F, we will delay shipping until the weather warms up. We ship by USPS Priority Mail, which, under normal conditions, should arrive within 1-3 days. We include a 72-hour heat pack at no extra charge. We want your plants to be healthy when you get them, not frozen!
