Oohso™ Cute Jewelry - Twoja Personalizowana Biżuteria review for Opus Cart Upsell Cart Drawer

July 7, 2025

I've been using OPUS since it was a startup, and I can confidently say it’s the best cart app I’ve ever worked with. Over the months, as my business grew and my needs evolved, OPUS kept improving right alongside me. I haven't found another cart app that comes close to meeting my store’s specific requirements — and believe me, I’ve tried a few. What truly sets OPUS apart is not just the functionality, but the incredible support team behind it. A special shoutout to Katie, David, and Lulla — they’re always available, providing prompt, helpful feedback, and going above and beyond to assist whenever needed. Since my store sells personalized products, setting up and optimizing the cart required extra attention and customization. The OPUS team handled this flawlessly, tailoring solutions that worked perfectly for my unique setup. If you’re on the fence about which cart app to choose for your Shopify store, don’t hesitate — go with OPUS. It’s powerful, reliable, and backed by a team that genuinely cares about your success. I simply love it!
