USO: Ultimate Special Offers

We like that there is a lot you can customize about this app. Customer service is excellent, and they can help you figure out exactly how to configure for more complicated promotions. It does almost everything we need it to do in working around Shopify's stupid refusal to allow multiple promo codes to be used on a transaction. I'd give it a 4 3/4 stars if I could, as there are just a couple other things I wish it could do, but it's by far the best app we've found for markdowns and promotions. We have been using for about 6 months and haven't experienced any of the glitches that we did with other apps. You can install and use Ultimate Special Offers with confidence.
