I want to place an order too, and received a promotional code by e-mail (it's one of those mentioned above).
However, after typing in the promotional code and clicking "APPLY," it does nothing to change the price. A "promotional discount" is shown, but it's the same price as what's listed on the website normally (for example, approximately $43 for DS sets). There's no additional discount.
I've e-mailed deepdiscount's customer service, and it says to wait up to 48 hours for a reply.
If anyone else knows what's up, please let me know!
