In many cases, the reason a Swag Code is not rewarding you with Swag Bucks is that you have entered the Swag Code improperly. Check to make sure that you have entered the code exactly as it has been given. If you have copied and pasted the code, be sure that you have not inadvertently added an extra space either before or after the alphanumeric sequence.
Other reasons why a Swag Code may not be working for you include the possibility that the Code is expired or that you are attempting to enter the Code on the wrong website, or you have used the code previously.
