In order to make a basic shopping cart available, these complex features were omitted and may be available in a more deluxe version of the shopping cart. No ability to handle tax, or shipping costs related to products ordered. Instead, this must be done with follow up contact after the customer has placed the order. However, you can inform the customer of this on your customized HTML pages, so they can expect a follow up phone call or email message. No payment gateway compatibility (in other words, no realtime credit card processing) is available. This will be in future versions. Not easy for novice web designers that do not know how to insert HTML code into their pages, or are not very technical. (ie: We do not have an online web wizard to produce the store) Heavy traffic testing has not been completed. It is recommended you do not place more than 10 products with an Add to Cart link on one webpage to avoid excessive CPU and memory utilization on the server.
