Some people have definitely figured out ways to fix this issue (sounds like you have), but for others the service that Swapbox provides means the difference between getting your package ontime and maybe never getting your package. I don't think that this solution is right for everyone, but I think that there are so many pain points in this space and Swapbox can solve some of them. Also, if there's ever anything perishable or you don't want to lug it home from work, check out Swapbox :)
