The Terms & Conditions are:
*This offer valid on purchases up to $500 per household. If you cancel, exchange or return your purchase, Points awarded for your original transaction will be deducted from your account.
**Points are available until 9/30/12, or until the maximum number of Points have been claimed. Once the maximum number of Points have been claimed, the offer will no longer be available and you will be directed back to the MyPoints website.
OpenSky points are different from Points earned in the MyPoints program and may not be used for MyPoints rewards.
The link to OpenSky has "Mypoints7500" in the link - I think that someone mistyped and that you are supposed to receive 15 MyPoints per dollar - not 150.
