As another US-based mail order tea drinker, you're likely going to have to stop using Amazon. There are some domestic sources, and some international that ship here. Will it be cheaper? No. And you may have to try a somewhat different brew. But you shouldn't face these problems and there are some great teas to be had 😋

There are a few tea forums on different instances but they're pretty dead. One or two have sourcing options, tho! I've used stash for a long time, but I drink loose leaf. Not sure about their bagged. I've heard Arbor is good, too, but haven't tried them.
