We highly recommend this particular strategy for advertising your business. The Write and Polish-mobile has its very own set.
They were provided by our good friends at The Sign Shop of Racine. The Sign Shop's vehicle magnets are high quality, resisting fading in the sun, peeling and other obvious weathering (which cannot be said of all magnetic vehicle signs; beware the low-cost, still-lower-quality vendors).
The standard order are for a pair of full color, 12" x 18" magnets for $75, which include a half-hour of design. Custom sizes also available.
If you are in town, then look no further: get in touch, send your art and/or discuss your ideas, approve your proof, and then hie yourself to their fantastic shop and enjoy a visit to pick up your new magnets.
However, even if you are far, far away, we would suggest it is well worth your while to order and have them shipped to you.
Sure, you can get less expensive vehicle magnets. But they will very quickly look cheap. And the last thing that you want to be part of the sub-text advertising your products or services is that you cut corners to save a buck!
