The online coupon site and the FTD flower company are giving refunds after getting complaints that a Valentine's Day flower deal wasn't so sweet.

Groupon customers were offered $20 off a $40 purchase from FTD last week. But some customers found the flowers were priced lower as sale items on FTD's own website. They complained on the Internet that FTD inflated prices for Groupon customers to make up for the discount.

But FTD President Rob Apatoff says that's not so. He says it was clear on the sites that the coupon didn't apply to sale items.
