UpBump ‑ Upsell Checkboxes

The reviews are overwhelmingly positive about the app’s ease of use, quick installation, clean appearance on store pages, and the value it adds to product pages and checkout. Many merchants praise the support team as exceptionally responsive, personal, and willing to go beyond standard help by providing step-by-step guidance and even custom or unrelated technical assistance. Several reviewers describe the app as simple, effective, and a strong fit for ecommerce brands that want a hassle-free setup and reliable service. The main negative feedback is limited but important: one reviewer reported that the app caused duplicated orders at checkout when items were added to cart. Even so, that same reviewer noted that the concept is great, suggesting the issue may be more about implementation or compatibility than the core idea. Overall, the sentiment is strongly favorable, with the app’s usability and support standing out most, while stability or checkout-related bugs appear to be the primary concern.
