RepeaterStore

The customer support is simply outstanding. Someone helped at literally 11:40pm in the evening (their time). Pretty damn impressive. And the app is wonderful too.

I'm not sure why some of the commenters below are so negative. So far the app has been really excellent and fills a really critical role - both editing old orders and adding new orders. Highly recommended. Update: They don't respond to emails, and editing an order breaks the fulfillment settings on the product.

Really simple app that works well. But I wish it showed all possible metafields for all products automatically.

These apps are excellent, and the customer support is excellent too. Highly recommended!
