Discount codes

[motofox4]

Last year I received a 40% off code for rooms and I think I remember around the same time (January, 2009) I saw a lot of other people got the same code. Do they usually send these out every year AROUND the same time or is it done throughout the year on a random basis?? I want to book a trip for September, 2010 and really would like to book using a discount and am wondering if I might be getting another code sometime soon.. anyone have any idea???

TIA!!
