Layaway Information

Layaway Policies

We offer a layaway plan on select products so you may pay for your order over a period of 60 days. Products that are eligible for layaway will show "Layaway Available: Yes" on the product page.

Here's how it works:

The total amount of the order excluding shipping, tax, or fees is divided into three (3) equal payments. The first payment is due with the order, the second payment is due 30 days later, and the final payment is due 60 days after the order.

There is a $15 non-refundable fee for layaway orders. This fee is added to the first payment along with the shipping and any tax. The first payment is made when the order is placed.

Example: Your order total is $300 plus $12.75 shipping and handling. If you select the layaway option, your payments would be:

  • $127.75 (1/3 of purchase = $100 + $15 layaway fee + $12.75 shipping)
  • $100.00 (1/3 of purchase = $100)
  • $100.00 (1/3 of purchase = $100)

If your initial payment is made by credit card, we will automatically process the 2nd and 3rd payments at the appropriate time using the same credit card information. You will be reminded via email that a payment will be charged. If you need to change this for any reason, please contact us.

For payments made other than credit card, payment must be received within seven (7) days of the due date or the order is subject to cancellation. You will receive a reminder via email that a payment is due.

If you wish to complete payment early and have your order shipped, you may contact us at any time during the 60 day period. There is no penalty for prepayment.

Additional products may be added to a layaway order without penalty. A new payment schedule will be calculated based on when additional products are added.

If you wish to complete payment early and have your order shipped, you may contact us at any time during the 60 day period. There is no penalty for early payment.

Cancellations of layaway orders are subject to a restocking/processing fee of 10% of the order total (not including tax and shipping costs). This restocking fee is in addition to the $15 non-refundable layaway fee.
