Ultimately as you have already pointed out, these are not all features found within the one theme itself, so it would require customization on your part if you were looking to implement additional features such as businesses being able to offer coupons/promotions on their listing (outside of adding information to the listing description). Our themes are not encrypted, so you are free to make modifications if you wish. Vantage itself is a stand alone theme, so when you refer to use with other themes, I assume you mean for styling. Again, this can be done through customization, and we would recommend the use of a
child theme if you are looking to make a lot of changes to the default theme.
Whilst AppThemes doesn't offer customization services, we do have a
certified partners page where you can find developers for hire who are experienced at working with our products.
No, this is not a live chat. We've used various methods to deal with pre-sales questions and currently this registration-free forum option has been the most utilized as the majority seem to prefer no registration required, which of course comes with the issue of non-notification. We may look at other more direct methods in future. Thanks.
