[quote name='chuckywang']These work on Blurays too?[/QUOTE]
They do, but you will find that for most of their blu-rays, even the 50% off the coupon only takes the price down to what you could get them for elsewhere at any time. The only real exceptions are titles that are generally expensive elsewhere as well, such as Criterion. The last time they had one of these 50% off coupons, I used it to stock up on a few Criterion titles in between B&N sales. Unfortunately, none of the Borders stores around here have gotten in the new Criterion titles that came out since the last B&N sale ended last month (probably, I'm guessing, intentionally, because this coupon was coming).
[quote name='BustaUppa']Are Borders online prices generally the same as their in-store prices?[/QUOTE]
No. Their online prices are generally discounted, whereas their in-store prices are nearly always MSRP. Note that this coupon is off of MSRP, so if you try to use it for an item that's on sale, you'll have a choice between either paying the sale price without the coupon, or paying 50% off of MSRP. They don't stack.
[quote name='keithp']You should get them in your email. They're always sending them to me.[/QUOTE]
Heh. I sent them a complaint a while back when they sent me an email advertising a "big sale", and I went to four different Borders stores on the (evening of) the first day of it -- one store "hadn't gotten around to" setting up the sale yet (they still hadn't four days later), two stores had no idea that there even was a sale, and the last store had a very small number of items out, nothing close to what was advertised. Their passive aggressive response, rather than, say, apologizing, was to simply remove me from their mailing list (though they conveniently continued sending the partner offers).

ers.
Since then, I get my Borders coupon links from Slickdeals -- it's actually the one thing that I use that site for. There's a very well-maintained thread over there which very nearly always has links to the latest Borders coupons (not going to link to SD here, but I'm sure you can find it with a search). As a bonus, Borders doesn't actually send every coupon to every customer, and sometimes they'll send some customers 20% coupons while they send others 30% coupons (etc.). But if you do manage to get any coupon (through a link or whatever, whether they sent it to you or not), they will honor it. So you can actually get a lot more coupons by checking there for them than you would if you just waited for the emails.
