Thanks for the bug report! I was able to duplicate the issue and I just pushed a bugfix. Please let me know if it works as expected now.

I love single page applications

Also, there are fewer than 1k lines of javascript in that html file

I think that's neat

Lol yeah that description came from a Samourai wallet fan who didn't like whisper addresses when they came out, but I embraced his criticism because it's true

They are a bip47 ripoff because I wanted a variant of bip47 that was compatible with regular bitcoin wallets, and whisper addresses are what I came up with

They were pretty poorly thought out at the time because I made them during a weekend hackathon so their feature set was extremely limited at launch. But nostr fixed some of their initial problems so they've improved since then

And in comparison with bip47, it's true that whisper addresses carry a higher risk of fund loss, because the data you need in order to recover money from them is not on the blockchain, it's only held by the buyer and -- in the case of this app -- also on one or more nostr relays in an encrypted direct message. You can lose your funds if all copies of the whisper key are lost, which is much less likely with bip47 because everything it uses gets stored on the blockchain

Yeah I didn't implement an inventory management tool

I recommend removing products when your inventory runs low

And if someone manages to order more than you have, offer them a refund
