Scored on 82 merchant reviews we hold for Cart Lock:Block Checkout Rules, across five checks. Every figure is computed from those reviews — expand any row to see the counts behind it.





Computed from the 82 reviews we hold, with 12-month windows measured to 2026-09. This scores the public review record — it is not a review of the software itself, and a low score often means we hold little evidence rather than poor evidence.

The newest 8 of 84. Open one to read it in full, with the developer's reply where there is one.

Possibly the most useful app right now in the store. Fast and reliable. I am zero tech savvy so I contacted support and in lest than 15 minutes all the rules I wanted to implement were running smoothly. 10/10 app. Looking forward to launch soon. Many thanks.

Works well. Good support. Recommended

Very happy with this app, it does exactly what we need it to do, even when we have complex configurations. Support is awesome at helping to get those set up correctly in place. Highly recommend!

Great experience at the time of installation to help with creating my first rule. Thansk a lot

Developer repliedThank you! We’re glad the installation experience was smooth and that we could help you create your first rule successfully. Show more

GREAT support when help is needed. I'd like to see one day blocking by last name but the customer tag or zip code blocking works for me.

Developer repliedWe appreciate the feedback! Glad the tag and zip code blocking works well for you, and thanks for the suggestion about last name blocking. Show more

Great help on figuring out implementation

I needed a tool to exclude a zip code from being able to choose shipping. This worked perfectly! Shahriar was very helpful and quickly got me the result I had been searching for.

Developer repliedGreat to hear Cart Lock solved your zip code restriction requirement perfectly! Glad Shahriar could quickly help you achieve the exact setup you needed. Show more
