I’m working on an e-commerce site for the first time in about 10 years. The site is Trés Spa, a skin care products company in northern California. Unlike my previous forays into e-commerce, none of the technologies I’m using come from Microsoft. I’m using the community edition of Magento. So far, I’ve been able to update the configuration so that USPS shipping options show up in shipping and tax estimates. I haven’t had to write any code yet, but we’ll see if that changes. Despite running WordPress for awhile, I’ve done very little with PHP.
