Thank you for the replies Dan & Mitch. Makes sense.
Congrats on getting it running to your specs!
I use Woocommerce products daily. I've tried almost every shopping cart available for WP and Woo has the best one I've found by far. I'll be sure and keep NETBilling in mind....In fact, I'm currently helping somebody build an eCommerce site and they specifically mentioned using your service. Hopefully it will go that way and I can check it out.
