You mean those spammers? I couldnt believe it when they emailed my corporate email address last week offering me serivces and to work on one of my sites. I am the owner of _lildawg_site_ and didnt need their spam (Unsolicited comercial email) nor would I trust them or their products. If you violate the law to try to get business why would I ever trust them. This is just my opinion on them as I was spammed by them and therefore really unhappy with them. I would recommend Boomers site (a forum admin here in x-cart) he offers his products as well as supports them.
www.cart-lab.com is his address.
Remember if you buy a modification from a third party seller they are advertising that it will go in with no problems. If it doesnt then you didnt get what you paid for. They are selling you somehting they say works if you followed their instructions and it still doesnt work then they must have a problem with their product.
