I am looking for a shopping cart system that is very very easy to add many new items daily with photos. Each item can only have a quantity of 1 and be moved to a sold section since they are unique.
As long as you setup the shopping cart properly, a system like Magento can be setup to add a product and display when it is sold out. Adding products is rather simple, but the Magento system itself has a very high learning curve. Not to mention you need a powerful-ish server to run it smoothly. I currently run a single magento install developing 4 different shops on that install on a 2GB RAM 2GHz CPU VPS. It runs smoothly and by adding caching our tests show excellent response times.
yes buddy the magneto will be the best shopping cart system for you if you have the high configuration upto 1 gb i have used the zen cart for it at 512mb ram it was too slow to be work on it. so i will advice you to move on to Magneto only Thank You
