Starting August 3, 2009!

If a new engine is in your future, here's one more reason to make sure it's an O.S. engine: Bonus Bucks! It's a special, limited-time offer, and it works like this: if you buy a new O.S. engine from an authorized Great Planes^® dealer or authorized online retailer between Monday, August 3, 2009 and midnight on Thursday, December 31, 2009 and trade in an old engine, you'll receive Bonus Bucks as a reward. They come in the form of a merchandise certificate which you can use to buy products from many of R/C's most respected manufacturers.

Any old engine will do. Brand, condition and displacement don't matter — it doesn't even have to run. Just trade it in when you buy your new O.S. engine — and you'll get Bonus Bucks in return! This offer is good on every engine that O.S. makes — and depending on the new O.S. engine you buy, you could end up with as much as $150.00 in merchandise credit! See the chart for the O.S. engine you want to buy, and you'll find the number of Bonus Bucks you'll get listed above it!

But remember: this offer is good only from Monday, August 3, 2009 through Thurday, December 31, 2009. Act now…and enjoy Bonus Bucks tomorrow!
