Layaway
Spread the Cost
Layaway Installment Plans
A layaway is an interest-free payment plan that enables you to reserve an item with an initial deposit, and then pay the balance over 60 days.
Layaway is very popular with Lillicoco customers, particularly when making a more considered purchase.
How It Works
In total, you will make three payments over three months:
Day 1: 33.33%
Day 30: 33.33%
Day 60: 33.33%
Your layaway purchase is reserved for you as soon as the initial payment has been taken.
Your order is shipped once the full balance has been paid.
All of our usual terms and conditions apply with a layaway purchase, although 15% of the invoice total is nonrefundable in case of cancellation or return, acting as an administration fee.
A layaway is not a loan, nor is it a form of credit. A credit check is not required to put an item on layaway, and missing a payment will not affect your credit score.
If you do not complete your layaway on schedule your reservation may be cancelled and your payments may be refunded, minus the administration fee.
