Interesting. My order went through without any errors. After applying the promo code, it was showing two x 20 discs for a total of $16.99. The email titled "order information" shows
DVD+R DL PLAYO|PDLPR2420C 2.4X % - OEM (Qty=1, Price=$16.99)
Clearly, the quantity is "1", but 1 what? The online order information status page is more revealing, it clearly shows "1 x 20". I have sent an email to Newegg explaining the situation and asking them to cancel my order if the promotional code does not work. I'll let you know what I hear back from Newegg.
