Looks like this weekend is a good one for free stuff if you are out and about.
First there's the free pretzels at Auntie Anne's (see details here).
Now there's free coffee at Border's book stores. You do have to bring in the coupon (available here) and be a Borders rewards member. But membership is free, and you can do it quickly online here.
The coupon is valid through Feb. 21.
Membership to Borders brings with it other perks as well, including in-store and online members-only specials.
