There are three (3) basic approaches that are strong possibilities.
1. Independent Shopping Cart System
2. Blog Based Product Listings with a Cart and a PayPal Button
3. Page or Post Based Product Listings leading to the PayPal Shopping Cart
Independent Shopping Cart System
This is the best choice if you are a truly organized and focused venture building a strong piece of web-based retail real estate. You don’t want to drive traffic anywhere else but home, and you want to protect your client list, traffic reports, accounting and shopping data like it were a pile of your own diamonds.
Blog Based Product Listings with a Cart and a PayPal Button
This is the quick and easy solution with the least amount of learning curve which can be implimented and operated with only a blog interface and a PayPal account. Many use it with great success.
Page or Post Based Product Listings leading to the PayPal Shopping Cart
If you want a full featured shopping cart, but don’t want to go through the administrative chores of independent venture setup, you should expand your PayPal account to utilize the PayPal shopping cart system. Just be aware that your customer will spend some of his/her time on PayPal.com instead of your website, and your shopping data is stored on PayPal.
