I stopped by Rockler in Altamonte Springs and verified the details of their discount offer. 10% off general merchandise for club or guild members. They have a book at the register and check a box on the club page for each purchase. After 20 purchases, the club gets a gift certificate. They made up a new page for our club, with my contact info. I got the discount on my purchase, so only 19 more to go.
I swung by Woodcraft just down the road and verified they also offer 10% off to club members. I saved $4 on some t-track clamps for my tapering jig. They don't track by club, so no further incentive.
