Synkro: Inventory Sync

I have been using this app for nearly 6 years, to integrate the inventory on 2 stores. I have now added a 3rd store and Synkro has to work between all 3, but only on selected SKU's
The app is superb, has never let me down, and works just as it should.
I have reached out for support only once or twice over the years and this has been quick, efficient, and effective.
What more can you want from something, this app is a great find and I'll continue to use it for years to come.
