Hello Marybeth- I have done various gift with purchase promotions over my 24 years in direct marketing. I have learned the lift depends on the value of the gift being given away and the threshold the customer has to spend. For example, a $10 free gift value on a $50 minimum order (20% given away) typically gets a 5-10% lift. I am happy to share more thoughts with you if you want to share the detailed promotion idea with me. Hope this helps. Cindy
