Hello all . .. so I sell cedar curtain rods . .and am trying to figure out how to combine shipping costs for my customers. If they purchase a 30" rod and a 70" rod ( all one order), it takes two separate boxes but I tape them together and ship them out. My customer may have to pay $40 or higher when it only costs me $20. Instead of reimbursing them like I always do, is there a better solution? Thank you in advance! Jan
