You have a brick and mortar store front, and its doing well. However, the idea of being able to take orders 24 hours a day from all over the globe also seems inciting.
I am a developer of a great product called Yahoo! Merchant Solutions. It is a fully integrated shopping cart, statistics and website platform that has stood the test of time. I personally started using them in 2003 and they have never let me or any of my clients in that time frame down.
This product is not recommended to anyone with less than 10 items. But there is almost no limit to how many items you can have, and for about $40 a month (payable to Yahoo!) and an industry standard small percentage per transaction, you can be open all day and night, all over the world.
And unlike some of those scary phpAdmin shopping carts, and those fly by night new guys on the scene, Yahoo! Merchant Solutions is dependable, easy to navigate and lets you focus on making money, not trying to figure out how it all works.
Here are some examples of eCommerce sites I have built using Yahoo! Merchant Solutions.
