Please do not use this plugin!!!!!! This is a scammer who charges fees indiscriminately. Previously it was 8.99, later it was 16.99, now it's 19, and he's still charging fees indiscriminately. Customer service doesn't even pay attention to you!!!

Update Again: We have the email proof that they spammed us begging for the review to be removed so please, let's get into that, and the fact they signed up to our email list and contacted our customer support on the website, BEFORE even allowing a response, is further proof of harassment. An app contacting you through your customer support on your website is taking time away from actual customers. Also, it was not within 48 hours, it was within 24 hours and even sending any more than one email within a 48 hour window is insane, but within 24 hours, harassment, especially when contacting us through our support line. AND no sir, that is not common practice for charging for an app, as there are plenty of others who only charge based on what THEY bring in to your site. Case and point, it took us 2 hours to find a new app, and have it running and converting same day, no issues since. I won't list that app here as that would be wrong to try to promote another app in a review, but everyone should look elsewhere. Updated Review: Stay very far away from this app and company. After leaving our review, we have now been harassed by the "owner" of the app! He sent us 4 emails in less than 24 hours in "complete shock" that we would "dare leave a 1 star review." He then signed up to our email list and then spammed our customer support button begging us to remove our 1 star review. He was flooding the chat that is for actually customers with actual questions!!!! This is the most unprofessional thing I have ever witnessed. Then come to find out, they charge you by the number of sales your website does, not the number of sales their app generates. What utter nonsense! "Original Review - The in-cart upsell widget suddenly disappeared from my shop without warning. Everything was still active and it had generated seven conversions in just two days. I made no changes to my store, yet it stopped showing entirely. No matter what I tried, it was just gone."

I won't list that app here as that would be wrong to try to promote another app in a review, but everyone should look elsewhere. (Never once did I say we were charged for anything, as we were in the free trial window, but the charges are not minimal when you are charging per order, not per order you drive. No one else charges like this.) You've also updated you response now 3 times and changed the number of time you contacted us after the truth was told. On top of that, you did not reach out via out contact form first. you spammed our emails. It's also inappropriate business in general to reach out via website chat and not email. I'm not sure how you do it, but email is the only appropriate way to contact a business as another business. Updated Review: Stay very far away from this app and company.

**Update: This company didn't like that I gave an honest review, so now they are making excuses, and wasting even more time by constantly emailing me, and replying to this review. I offered for them to fix the issue and I would take this review down, but they just badger me instead. Shameful behavior. Proceed with caution** Service is terrible. The app wasn't working and they had me get on a call late at night. Then the Rep was asking me what the problem is. I had already wrote a detailed description that the rep didn't bother to read, and then she wanted me to direct the call. I can't direct the call! If I could direct the call, I certainly wouldn't be contacting them. Just such a waste of time for something that doesn't work. Don't offer support if you're not going to provide it. It's that simple.

The add to cart function was not working. The support didnt care and took 10 min. to write any message. So I wasted almost an hour without any solution or any information when a solution is expected. Looks to me like the employees just didnt care, try to waste time! Its a risk to relie on such an app, when not even basic functionality is working and this useless support structure!

Problemas catastróficos após deletar este aplicativo de minha loja, pois não estava funcionando mesmo eu configurando e buscando respostas tanto com o chatgpt, quanto com videos no youtube, ou com o tutorial que eles oferecem, simplesmente após deletar o app de meu site, um produto que selecionei dentro do app congelou na minha loja toda, acredito que ficou congelado junto com o deletamento dele no processo, por favor, consertem isso imediatamente!

I just installed the app. And now i am forced to get Free Trail. While i don't want trail i want to continue with free plan. But in app screen there is no other option but only proceed with forced trail. This is completely inappropriate UX. Shopify must check this kind of practice and remove this flow.

The bundle isn’t working correctly. When I change the product size from the dropdown, all prices should update automatically, but they don’t. Also, only two products are showing as bundle options on the product page.

Beware of the app!!! The hidden cost is crazy!! They are not charging the price tier. The app charges EVERYTHING!! You use it, the cost will be very high!! you don't use it, hah still charge you, that's why the user guide about the price is wordplay!!! Terrible app, terrible company!!!!!!!

I really wanted to love this app. The features are useful, and it’s well-integrated with Shopify on the surface. However, I discovered that it causes ghost Purchase events in Meta due to how it uses Shopify’s AJAX API. This inflated my conversion data and hurt ad performance. Support acknowledged the issue and is exploring a fix, but it may take 4 weeks, and even then, they said a solution might not be possible and. I had to disable the app and revert my setup disappointing, especially after investing so much time setting it up and running it for 30 days before identifying it as the source of the bad Meta data. If you're seeing ghost Purchase events with $0 value in Meta, this could be the reason. I’ll update this review if a proper fix is implemented.

After 50 orders you will be charged $6.99 for each 100 orders you have in the past 30 days. They like to not mention it. But I will.

Lost sales by using this app. The popups freeze on customers leaving them stuck at checkout. They fixed it on one of the offers, but it kept happening and I no longer trust it.

Beware that this app doesn't work for Iphone. Specifically, if you have different offers the first upsell pop up doesn't show up. The customer service doesn't care about your problem.. they said they were going to share this problem with their technician but nothing has been done and I haven't received a single e-mail from them. The zoom call was completely a waste of time, the staff didn't know what to do.
