This is the second ever thing that I have made for CS-CART, I hope you like it!
Basically, it is a price match request tab, the information it will ask for is:
Direct Website to item:
Price to Match:
It will support captcha images if you require and the request will be sent to the email that you configure.
Please let me know if there is anything I can do to improve this add-on!
Do you have this add-on for 4.1.1
I haven't used this for any V4 store yet, but it may be useful - Price Match CSCart.biz
