The super coupon says:
Cen-Tech 7 Function Digital Multimeter (Item 98025/69096/90899)
Reg Price: $9.99
NO PURCHASE REQUIRED!
Official terms from the coupon itself:
Cannot be used with other discount coupon. Coupon good at our retail stores only. Offer good while supplies last. Shipping and Handling charges may apply if not picked up in-store. Non-transferable. Original coupon must be presented. Valid through 5/28/13. Limit one coupon per customer per day.
Assuming most cashiers will simply scan in the coupon's barcode (as they are accustomed to these product giveaways), the stricter terms of this coupon should not present too much of a problem. YMMV, of course.
