Thousands of stores are being created online everyday. If you think, these people are redoing stuff over and again, you are wrong. People use the following free and open source software for building websites and online stores.
1. Magento
2. OS Commerce
3. Zen cart
If you are stating a new store, I should point out that the latest software, which is being trusted by any is “Magento”. The software is free for use, and quite easy to manage. The install process is not very easy though.
Magento offers shopping coupons for store owners, you can easily create a store out of the box and create coupons, track coupons, edit them easily using this software. I strongly recommend magento for online store coupon software.
