Thank you.
I actually don't know the difference between 'Post' and 'Get'.
However, I once received the following CMS reply in a ticket I opened up:
- "If you are using "System - Page Cache" the submit method has to be set to GET. Joomla is caching the pages based on the URL."
1. No, the offer decreases when the get deal button is clicked and the coupon is generated.
2. The difference between 'Post' and 'Get' is that when using GET the http parameters are added to the URL.
3. Yes, we can add this on the next release.
