we used a 10% coupon code in the animated ad
Be aware that there are user groups online who share information with other shoppers when they spot something like that.
Overuse of coupons trains shoppers to assume that the normal retail price is a ripoff.
A remarketing campaign will likely be just a small piece of your overall promotion, but they can be nicely productive.
For one merchant whose stats I've seen, their remarketing campaigns accounted for about 1% of their total AdWords cost, but generated about 3% of the sales from AdWords. That merchant did not use coupons, they just ran a few extra of their ordinary banners in front of users who had abandoned their shopping carts.
One of the big secrets of successful remarketing is to keep a light hand about it. Set tight limits on how often your remarketing ads appear, so you don't make the user feel stalked.
Also, if you over-show your ads, the clickthrough rate will go down and that will push your costs up.
