Groupon is offering an easy to set-up E-commerce store. I was able to get mine set-up in less than an hour. Once approved, that took a week, I began taking 1-3 orders per day.
It's great right now and no competition for my product and the way they monitor who and what you are selling I hope to hold this category!
I now use the ShippingEasy CSV to import the orders but it would be so much better if you would integrate into the Groupon store so that orders come in automatically and the tracking info is submitted back through the store as well.
