<prompt> Human: Im planning on buying a nice camera online but Im worried about interest and also theres a chance I might return it. Camera with the lens is going to be around 2k.Also not sure when the time period kicks in. If my card says payment due date is Aug 1 - then if I buy the camera Aug 2 and pay it off before Aug 31 - will I avoid interest?  <response>: as long as you pay the statement balance in full by the statement due date, you wont get charged interest on your credit card.
