Core. review for Appstle℠ Bundles App & Upsells

We had good experience with good customer support on other shopify apps, but so far Appstle guys are at the very top. They are the best. They are not jsut answering quickly, but truly finding a solution to your issue, even if you are not a paying customer yet. And on top of that their pricing model is very correct, unlike some crazy pricing from other shopify apps.
