New Post: Request for quotations

All text in the store is somewhere and can be changed, so don't make your choice based on that.

Text is either in the back office settings and templates, or it is in the module resx files in the module folder, or it is in the core DNN resx files in App_GlobalResources.

The select payment method you're referring to might be the fieldset label. That'll be in the module's resx files, but there is now also a class on the fieldset that can be used to hide it via CSS if necessary.
