Painkiller BG Shop

Very easy to use, and great tutorial in the Apps. Just have to read the guide and everything go smoothly. The team has quick respond after I send email which I had the issue of the code. They really does great job for fixing the issue (Less than a few hours!). With the free plan, the functions are definitely enough for small / medium online store. Once the store contains more items and pages, you may want to upgrade the plan for more service. (Much more worth than other apps which charge $20+/month.)
