Layaway means paying for items with an initial down payment followed by smaller installments paid over time. Retailers will keep the merchandise while you pay small installments over a specific period, determined by you and the retailer. Once you have paid the total amount owed, you can pick up your items. Layaway does include flat fees, but there is no interest associated with the purchase.
Layaway programs do not run credit checks for you to use, you simply need a proof of identification. The downside to layaway is that the fees can be high and if you are unable to complete the payment installments over time, you may be charged additional fees to leave the agreement.
