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.

In this scenario please then allow 48 hours for dispatch. We offer free delivery throughout the UK when you spend over £175.
Dispatch times may vary during peak period – please contact us if your order is urgent.

Any specific delivery instructions please make a notation in the designated "delivery instructions" box during checkout. Failure to do so may result in additional costs incurred by us for reshipping or holding your order. Please be advised that failure to provide such information, including business closure dates/times, may result in an invoice being issued for these costs.

At Lil Packaging® we are working on making FREE SHIPPING an option for locations beyond those already available in the UK. But like all good things, it's going to take a little time. Until then, simply use the UPS delivery cost calculator in your shopping basket to help you figure out the delivery charges that will apply to your location, and your prospective order.
We may deliver goods by separate instalments. Each separate instalment shall be invoiced and paid for in accordance with the provisions of the applicable contract. Each instalment delivery will be a separate contract and no cancellation or termination by either party of any one contract relating to an instalment will entitle you to repudiate or cancel any other contract or instalment.
Some deliveries may require TSS codes or EORI numbers. Please read our EORI and TSS guide here.
