There is no such template in the mendix marketplace.
Which does make a bit of sense, since Mendix is a app dev platform for enterprise apps.
B2C websites like a webshop isn't the target for Mendix.
Hi Abhishek,
You can have a look at this Grocer Scan and Go template which has an shopping cart for some inspiration: https://marketplace.mendix.com/link/component/207209
