If you are someone who has shied away from Coinstar because of the service charge that you must pay, here’s another reason to look at them especially with Christmas approaching. If you have more than $40 in change lying around you can get a $10 bonus if you put the $40 onto an e-certificate for more than a dozen retailers including Amazon, Eddie Bauer, Borders, Cabela’s J. C. Penny’s, CVS and more. The offer expires December 6 a few weeks before Christmas, but you can take advantage of the offer and have your shopping done early or get a little bonus when you do your shopping.
