I found something on the Acuvue website that might interest you. http://www.acuvue.com/buying-rebates.htm

It seems as though you need to buy in bulk to get a rebate. Here's an example:

ACUVUE® OASYS® Brand with HYDRACLEAR® Plus
• $50 New Wearer Rebate with purchase of 8 boxes
New Wearer rebate only for new ACUVUE® OASYS® Brand with HYDRACLEAR® Plus wearers.
ACUVUE® OASYS® Brand for ASTIGMATISM and ACUVUE® OASYS® Brand for PRESBYOPIA are not eligible for this rebate.
• $25 Rebate with purchase of 8 boxes
For current wearers of ACUVUE® OASYS®
