    Luis Maldonado:
    If i want to implement it with a custom template that i have now, does the javascript files need to NOT be bundled?. Will it work with custom template?
    Posted On: May 27, 2017
    Admin:
    Hi Luis, Thanks for your interest in our product. About your query whether the javascript files need to not be bundled, would you like to bundle all javascript fildes into one file only? In fact, as long as a script has tag <script>, it will be deferred automatically when our module is enable. Besides, we would like to offer free installation and money back guarantee as our Terms and Condition: https://bsscommerce.com/terms-conditions If you have any further queries, please feel free to contact us. We’d be happy to help.
