Just tried to run price-alert and I was getting the

Didn't find the 'price' element, trying again later

Now it looks like Amazon is wanting me to enter a Captcha.

Great little script! Just wanted to give a heads up for email config for use in gmail (US). I repeatedly received smtp related errors, even though other code examples seemed to match your code. The errors included "failed to login" (your logger code) as well as "smtplib.SMTPServerDisconnected: Connection unexpectedly closed", along with a few others.

Resolution: Going into gmail settings (https://myaccount.google.com/lesssecureapps) and turning this feature to 'ON'.

This may save future users some time if configuring with gmail (US) at the very least. Other than that, like the script and plan to modify it to fit my needs. Cheers!

I've attempted to modify the script so I can check warehouse prices... Seems my skills are not up to the job :(

I'd like to pull the prices from a page like this:

https://www.amazon.co.uk/gp/offer-listing/B014GXQ9YW/ref=dp_olp_used?ie=UTF8&condition=used

I know it's outside the scope, but was wondering if someone could help me achieve this?

This only works if the JSON file has 1-2 items maximum. If I try the code with more items (more product link IDs), then i get errors. Not sure what the solution is, or even what the error is saying.

Let me know if you have any idea, ill try to figure it out as well!

Tried to use the script this evening, but keep getting:

Didn't find the 'price' element, trying again later

Even though the xpath_selector seems the same. This is with UK site.

I've just made few changes in config.json file and when I run the script I face this issue. Any fixes?
here's my config file.

Congrats for the script. It's working , but after checking about 100 items it gives the message:
Didn't find the 'price' element.Trying again later.
and it's emailing me for every other item without reason for alert. However, it's all working again in a few hours , so I guess amazon just temporary blocked the ip address.
Any suggestions how to change the proxy between the JSON items?
Many Thanks

Hi! I have a problem using the script in my network, because the proxy isn't allowing to send the email. Could you help me to modify the script or tell me how to use a proxy settings?

Thanks!
