Returns and Refund Policy
Below you will find our returns policy – which is all about YOU.
We want you to be 100% satisfied with any order placed with us. Therefore if you are dissatisfied with your purchase and wish to return an item you may contact us by email at sales@lilpackaging.com within 30 days of your purchase, stating the reason for return*. We will then supply you with a return address and returns number, which is very important because no goods can be returned without a returns number.
*If the correct goods have been sent and you've made a mistake whilst placing the order, we are happy to accept returns for a refund, but you will need to cover delivery costs. All returns must be organised within 30 days of receiving your order. Items must be unused, undamaged and still have their original packaging and labelling attached. Nothing in these conditions affects your statutory rights as a consumer. The credit card or PayPal account used for the purchase will be credited with the original purchase amount (less any delivery charge paid where appropriate).
For made-to-order products (including our 9000 pizza style postal boxes), unfortunately, we cannot accept returns if you have ordered the wrong size or if your product doesn't fit.
Returns on Digitally Printed items
In the unlikely event of your custom packaging arriving damaged, missing items or is of incorrect specification (outside of the print, material specifications and variances as stated on our product descriptions) then please contact our mail happy team on sales@lilpackaging.com who will be more than happy to help you put things right.
As these items are made to order, we can only offer returns if the items you purchased are deemed faulty.
In all instances, if you’re not happy please do give us a call - we will do what we can to help you.
To avoid disappointment, we always advise that you order 1 unit to test out our service before committing to a larger order.
