Christianaudio.com just sent me an email telling me about this promotion.
Spend $10, get a $20 gift certificate. That amounts to getting up to 50% off of any of their products. You are allowed to gift them to yourself. And, I don't see anything stating that use of these is not allowed on sale items.
Apparently you can get as many of these deals as you want or can afford. The one caveat is that you can buy only one of these gift certificates per transaction, for some reason. So if you wish to buy multiple cards you will need to checkout multiple times.
There are no other major restrictions. But they do caution you that you must "have ONE $20 gift certificate and NO additional items in your cart for the $10 discount to be applied."
The offer ends Christmas Eve.
Here's
the webpage to go to to find out all of the details and to make a purchase if you wish. There's even a gift certificate voucher that you can print out and give to some lucky recipient. Really nice if you've waited to the last minute and still haven't gotten a present for a local person. But none of us ever wait until the last minute though, do we now?
