Missing 2 features
We've saved a ton of time and made a lot of money through this app. However, there are two features missing that have caused a lot of headache.
First, if a customer orders on eBay, your store is automatically updated. BUT if someone buys on your store, eBay IS NOT UPDATED. We've run in to multiple scenarios where we sold out of our store and then someone on eBay would buy and we'd have to cancel the order (and get penalized by eBay). This has cost us a lot of money.
Second, as one review already stated, if you update the SKU on your store, it will not register with eBay (even if you change it on ebay). You have to end the listing and re-list. A real pain!
Other than that, it has been a great time saver and money maker.
