Unfortunately, you cannot.
Groupons, Living Social, and other similar third parties sell vouchers that can be redeemed for our products on our website. E-Deal Vouchers are a similar type of deal, but our internal version of that.
You cannot use a third party voucher to buy one of our internal vouchers. Voucher can only be applied to our products and services, not toward other vouchers, including our internal ones.
You can use a third party voucher, such as a Groupon, toward an order. Or you could use one of our E-Deal Vouchers toward an order. However, you cannot use a third party voucher like a Groupon to purchase one of our E-Deal vouchers.
