Golang lambda function that runs daily, checks a list of product pages, and notifies you if the price you set it to watch for is reached.
Built with Golang, MongoDB, AWS Lambda
Upload the main.zip to AWS Lambda and set it on a daily trigger (You can use Cloudwatch events for this)
I use it with the ESP Mailgun, but it should be usable with any email provider of your choice.
