One of cs-cart developer quotes me 2800 Doller for this customization.
Thats why many developers adviced me that not switch to cs-cart.
I was developed a seperate website in laravel shiper.in for shipping cs-cart orders, total cost of developing from scrach was approx 180 Dollers.
Cs-cart is good but practicing very old design and UI. i have searched on codecanoyon there are many php scripts for multivendor. Also Flux store for multivendor is much better than cs-cart mobile application under 200 doller.
When i checked on cs-cart official site there many client website is not working or very old. Something cs-cart doing wrong and they are not realising.
