Most good sources tell you their resend policy at the time of ordering, I see more and more that will only resend 1/2 of the original order and some will not resend at all. Don't forget that customs keeps a record of all seizures, they don't flag your addy in the sense that they search through the millions of packages going through all the ports of entry for your addy (some people actually believe they do this which is complete nonsense), but if too many seizures show up going to the same person they can take further action so I'd be carefull about having too many packages sent to an addy with a lot of seizures on record.
