Shipping box manager did not work out of the box so I paid to have Numinix install it. They had some issue getting it to work but after a couple of weeks they got it to work. The addon works great for my products since I was getting killed on dimensional weight charges. If you are going to pay someone to install pay Numinix.

Numinix has made a top flight module for the Zencart platform! Thank you very much!

Excellent service. Well done. Like their various other products for zencart also.

This mod was exactly what I was looking for as I couldn't get 'Stock by Attribute' to work with the newest update of ZenCart. I also love the added features- like the Dynamic Attributes compared to 'Stock by Attribute'. I wish there was a bulk feature but other than that small flaw it works 100%, kind of a pain to do each product one at a time and as long as you don't have too many attributes it goes pretty quick. They installed this mod without issue, and I will use them to install future mods.

I purchased this service and my site speed went from an E to an A and my loa time was reduced by around 7 seconds. Would definitely recommend it.

I purchased this service after buying a theme on Wordpress/WooCommerce and it made my website the fastest loading in my industry. Thanks Numinix!
