I need a process diagram with swim lanes using gliffy or something

You and your business partner Alex started a small e-commerce firm selling high-end precision-manufactured gifts and toys (such as Gmbc, fidget spinners, and ForeverSpin Spinning Tops) through a web-store. These items are designed by various startups in the USA and other countries and manufactured in China. Your company procures items in small whole-sale batches from these suppliers and retails individual items through its own web-store. Your monthly sale revenue is about $50k. Your company does not have an office; you and Alex operate from your homes; to store supplies you rent a self-storage unit.

Alex is responsible for sending purchase orders to and procuring items from the suppliers, processing customers orders, packing and shipping items to customers, and keeping accounting books. You are responsible for setting up and maintaining your companys website, the web-store applications front- and back-end, transactional and customer database, and all other components of the enterprise IT infrastructure.

In order to operate efficiently and effectively, and to find opportunities for improving your operations and your customers purchase experience, you and Alex need a clear shared understanding of the business processes. After several discussions, you decided to document your shared understanding as a set of business process models. The first process you decided to document is one of the core processes of your business a customer making an order in the web-store. Since your company has been operating for a while, you decided to begin with modeling the existing process.

The process is as follows: a customer places an order by completing the following steps via the web-store interface:

1. Shopping (browse/search for items, select an item, select design/size, select/enter quantity, add to the order, review order); 2. Shipping (fill out shipping information, select shipping option); 3. Paying (enter payment method data (e.g., CC number, expiration date, CSV code), click "Check out", validate CC data via payment processing service; if data is correct, process payment, otherwise return error message and then prompt to enter payment data again; if the customer does not have a valid payment method, they need to be able to choose not to continue and close the web-page); 4. Receiving order confirmation/receipt. The customer needs to open the web-store page in a browser to begin making an order and to close the browser after getting the receipt. The customer interacts with your web-store system similarly to any other e-commerce application (such as eBay, Amazon, Etsy); the customer needs to be prompted by the application to enter any information.

Your online store system needs to prompt the customer (display relevant data input interface), show respective output in the browser, validate payment method (by sending data to and receiving response from a payment processing service), process payment, and then concurrently display and email the order confirmation/receipt.
