Hi Tony! Always a pleasure to see another kiwi pop up here ;)
In answer to your questions:
1. I'll do my best here, considering I've not heard of the other product before.. and believe me, we get asked to "convince me to buy this vs that" a lot ;) What I do know is that many of these similar themes offers by various companies do offer similar functionality/features. What's next to consider is who you're going to be dealing with, what their products are like etc and when it comes to AppThemes, for starters our
ClassiPress theme itself was our flagship product, so it has had a lot of time/attention invested into development and improvements making it a very stable product. Our themes are well coded and commented, we have a dedicated support team and our community is well established, and you have the freedom to make modifications or extend the theme through
marketplace products. If some of the customer sites in
showcase alone don't encourage you then I'm not sure I can talk you into it ;)
2. No I don't believe so, PayPal is commonly used even by other NZ sites so you probably wouldn't even need to look at other available
payment gateway plugins. And yes, theme uses Google Maps settings which do accommodate NZ so there's no problem there.
3. Yes definitely, you can just pay the difference. You'd email us for a special coupon code which will take into account your existing purchase.
Thanks
