"Tach-it"

If you have any realestate salespeople in your area , they frequently have magnetic calenders that you put on your refrigerator. If you remove the plastic coating on the frig magnet, you have an inexpensive/free "tach-it".
If any adhesive remains, you can remove it with "goo-gone", found in most craft stores.
Flyfishing on the cheep !
