For UPS w/Signature if you are not there, UPS will keep the package and try again the next day. They will try three times and then return the package to sender. Unless something has changed very recently, they do not let you choose special delivery times. However, you may be able to go get the package from your nearest UPS depot. Check where that is though, as it may be quite a ways away. Your best bet is to just have the packages left at your door, or get a trustworthy neighbor who is home to receive them.
