Avoid this app. For every item fee you want to add it creates an entirely new/separate "product" that appears in your cart, which is unbelievably ugly and confusing to customers. So if you've got 10 actual products in your cart, you've also got 10 fee "items" in your cart, on the receipt/invoice, etc. It's a really poor way to go about adding item fees and it blows me away that anyone thought to create an app around it. Granted, it is probably this way due to their inability to do anything on the Checkout pages (Shopify rules), but its still a pretty awful.

It also creates an unbelievable number of products in your database. I only have 7 real products and I've already spent the last 15 minutes deleting, literally, hundreds of these things.

I'm giving this two stars because the support can be helpful. They did a good bit of customization for me, perhaps knowing how awful their app is, but in the end it just wasn't enough. I hired an expert who customized code in about 30 minutes that is lightyears beyond what this app does.

And while support can be helpful, if you're in the US, beware -- they're in Belarus and so the end of their day is 11am PST, if you're lucky. So unless you want to wake up at 3am every day to try to get this working, you have to wait 24 hours, usually, for a response to any question you have. Pretty painful stuff. We were glad to be rid of it.

Thank you for your candid feedback. At the time, creating separate products was the only way to bypass Shopify's core limitations on adding fees, but we completely agree that it wasn't the most elegant solution. Since then, we have evolved with Shopify’s new Checkout Extensibility, which allows us to add fees without cluttering your cart or database. We’ve also expanded our support coverage to better serve different time zones. We appreciate your input as it helped us build a much better version of the app. We are looking forward to having you back to resolve your issue as soon as possible.
