Going forward, please submit all freebies as 'Product' deals even if they come via a coupon. Set price to '0' and do not set shipping (leave it blank). Add "(in-store)" to the title of those freebies that required store visit.
This seems to make more sense as doing so enables us to filter out all freebies using the menu including those that are really coupons. It also helps me with assigning daily prizes properly (I recently awarded two freebie prizes by mistake since one of them was a coupon
P.S. Direct link to all freebie offers (that you can also get to using the menu on deals page): http://www.buxr.com/freebies
