Posted this in another thread but some people here might still need.
For anyone still looking for notifications of stock, or anyone who I'm running the script for currently, follow these steps to setup stock notifications.
Install Telegram from the AppStore, set a username in the settings of Telegram, then compose a message to iphonestockbot
Type /start then /register
Then /stores and /models to find the stores and model codes you want to be notified of stock at.
/addmodel modelcode
/addstore storecode
To see what's on your watchlist do /watchlist and it will tell you.
When you have got your reservation and don't want notifications anymore just do
/removestore storecode
OR
/removemodel modelcode
For all the stores/models in your watchlist. I might add a /stop command that does that for you.
