FBP | Fast Bundle & Upsell App

We used Fast Bundle extensively for mix-and-match promotions, tiered pricing, and bundle campaigns for our Shopify store. When the app works, the concept is great and some of our previous campaigns did perform well. However, the overall experience became too inconsistent and time-consuming for our business.

The biggest issue was reliability. We repeatedly ran into situations where discounts would suddenly stop applying correctly, carts would not update properly, or promotions that previously worked would stop functioning after minor changes like updating pricing. Every sale launch seemed to require hours of troubleshooting, testing, rebuilding campaigns, disabling other apps, and trying to identify conflicts ourselves.

We upgraded our plan and spent over $300 expecting a smoother and more dependable experience, but unfortunately the amount of time lost troubleshooting recurring issues outweighed the benefits for us. Support responded, but many of the issues continued happening repeatedly without a permanent solution.

For businesses that rely heavily on promotions and bundle pricing during high-volume sales events, stability is extremely important. In our experience, the app created more operational stress than convenience over time.

I do think the app has potential and may work well for some stores, but for our business needs it ultimately became too unreliable to continue using confidently.

Nope, I have just installed this app to check its capability and compatibility for my store that was couple of months ago and I did not subscribe to them. Later did I know that I have been subscribed due to their weird scheme that it will be auto subs and cannot be cancelled unless you contact their support, we'll guess what, you will get a faster response from their support if you get their higher tier plans. $19 every month for something that I'm not using.

I'm using a lot of apps, and none of them does this scheme.

They started charging me $20 a month when i did not sign up to pay that. That is OUTRAGEOUS be careful what you install and hidden fees.

I honestly have no idea how this app manages to have so many positive reviews. The quality is downright awful. It’s full of bugs and barely functions. I had the misfortune of finding out from my own customers that their orders were packed incorrectly because the app simply refused to show any information indicating the items were part of a bundle. It didn’t even appear in the app’s analytics. For a moment I genuinely wondered if I was losing my mind, but after checking the purchase session recordings it became obvious that the app just wasn’t working at all.

I ended up spending hours calling customers and apologizing that the Christmas gifts they explicitly ordered as bundles arrived thrown together in a plastic bag all because the app gave zero indication that the order was bundled. I’m honestly shocked at how poorly this thing was built.

And even then, instead of immediately ditching it, I gave it a chance. I assumed maybe I had set up something incorrectly, so I contacted support. They really did try to help and managed to fix a couple of issues, but the deeper we went, the clearer it became that the whole app is just beyond saving. In the end, I still had to look for an alternative because every “fix” only revealed more problems. It’s useless, plain and simple.

And the pricing Genuinely laugh inducing.

I liked the app at the beginning, but what I really hated was the fact that even under the PAID account, everything is very much segregated.

The value just isn’t there unless you’re on the highest of all tiers. Even with a PAID plan, the promotional tools and campaign options feel very restricted with your needs, and support is minimal (unless you upgrade of course) and LONG.
It’s disappointing to pay for a service and still receive such low access to features and promotions to be honest, it is very discouraging even talking to the support team when you are informed on more things you lack in your PAID plan.

I hope the team can improve fairness across all paid tiers so every customer gets proper value and support - rather than making them feel lesser as a customer because their paid plan isnt the top tier.

Support was fast but useless, app didnt intergrate with our theme they asked us to change our re design our site so it would fit then found a work around adding liquid codes to each checkout option which only worked half the time, would not recomend.

In order to test and see if the app will work for your store and customer checkout flow, you'll need to contact their sales team. And of course, wait for them to approve (or deny) your request for a trial.
Some of the documentation suggests the existence a 14-day trial, and some suggests that the trial period is only 7 days.

Don’t waste your time — it doesn’t work properly. It even charges for free products. It’s terrible. Their good reviews must be fake.

This app is ok for product page bundles but DO NOT use it for collection page bundles. First off it take about 2 hours because of how bad the support it. its also so complicated they need to get their technical team to do it because the regular support doesnt know how to... There are better apps guys. dont waste yoour time...

Claimed they had a free version but it was actually only applicable to "approved sites in development". LOL
