Through Sept. 30, you can get a free 100% rebate on a single, full size Dulcolax Suppository. The fine print reads:
Purchase any one (1) Dulcolax® Tablets 25ct+, Dulcolax® Suppositories 4ct+, Dulcolax Pink® Tablets 25ct+, Dulcolax® Stool Softener 25ct+, DulcoEase Pink® 25ct+ or DulcoGas® 18ct between 9/13/15 and 9/30/15 and get a Visa® prepaid card by mail of up to $10.00 on the purchase price (excluding tax). Rebate request must be received at the mailing address or be postmarked by October 15, 2015.
They have a form you can fill out and print to mail with your UPC and receipt. I also found a free $2 Dulcolax coupon to help make the initial purchase cheaper! Awesome, now I can publish this and stop researching suppositories.
