This year 1/12 of the entries have a $5 coupon with the rest having a $1 coupon, making an average value of $1.32 per entry.
Also you can only use $200 at a BB store rather than $300, although they lifted the restriction on buying an iPod. Not that I'm gonna buy an iPod, but it's good if you're planning on getting one.
Also they're slightly reducing the number of tickets reserved for mail-in entries. This, coupled with the fact that I got a few "sorry, we're outta tickets" letters last year, is guaranteeing that I'm sending in all of my entries on the day the contest starts rather than spacing it out like last year.
Also since the rules aren't as favorable, I'm only sending in 500 this year rather than 1,000. Not yet sure what I'm gonna do with all of that Best Buy credit, but I'll find something.
