That is true, if you are used to the current state of Chinese vendors and having to pay $30 shipping for domestic shipping for smaller orders (below $300). But at least PGB uses FedEx (ground?). So in some way, PGB was ahead of its time, including with requiring crypto.
"Back in my day" (this time last year), domestic USPS shipping was free from SRY, as it is with some domestic kit vendors now. So I have refused to pay more than $10 for shipping. Uther's US warehouse has a spotty selection but shipping is free.
PWGrove's $15 shipping is partly why I have refused to buy anything from their website, since it reminds me there is no guarantee I will get the package. They offer insurance, but I'm not filing that claim.
