I've looked at the features and your demo but am not understanding where my tax and shipping information is set up or is that something included in the setup and is just part of my store? Can I change that if I need to, if so do I contact you with the changes? Other then adding my categories and product is the store ready to go with all that is needed after your set up is done? If not what else would I need to do on my end to have a smooth running site, how do I collect on purchases? Do you set that up too?
