Trunk ‑ Stock Sync & Bundling

I've been selling on Etsy for 5 years and just started a shop on Shopify and just made my first sale there. So far inventory syncing is working great and there are no worries about over-selling. Just for start-ups and also due to current exchange rate (weak JPY against USD), I feel the cost for subscribing TRUNK is a bit high. But I definitely need this app for operating multiple shops. Great app.
