Shopping carts are a necessity for businesses offering their products for sale on their site. Joomla, Magento, and other online store platforms can be found in many web hosting plans as integrated features. Some also offer additional eCommerce tools like ZenCart or PayPal. Review your options for eCommerce integrations so you can choose the one that makes the most sense for your store.
It shouldn't come as any surprise that, like other web host providers, A2 Hosting's unlimited plans aren't actually unlimited. It expect you to use its service like "similarly situated customers." This is like being on a highway. If everyone is going a few miles above the speed limit, you're probably okay, but if you're barreling down the fast lane past everyone else, you're probably going to be asked to slow down.
