Varina Goods Co review for Duplicate SKU Sync Master

This app is great! I sell personalized laser engraved tumblers in a much of different colors. Each color has its own SKU, and each SKU is used across a large number of product listings. This app lets me accurately control the inventory so I can keep track of how much product I have in stock. I tried several different inventory control apps before I settled on the one. The price is right an the support is great!
