Online retailer Firebox has launched a Christmas promotion called ‘20 prizes on a little donkey’, giving customers the opportunity to win a prize each day until December 20.

Anyone who makes a purchase from the quirky online gift retailer from the December 1-20 is automatically entered into the prize draw. Prizes include a Macbook Air, a Sony 3D TV and an iPad.

Details about which product is up for grabs are revealed each day to the retailer’s Facebook and Twitter followers.

Firebox head of marketing Pete Danks said: “We wanted to create something that was a bit different from all the other festive giveaways that are run at this time of year. We wanted to offer the lowest possible barrier to entry so all people have to do is buy something from us.”
