I would think it is only a problem if the your page(s) changes or no longer exists (that would a problem for them). Why not have them just link to your exact url? Also to my understanding, if a link has more than one redirect, page rank is lost in transfer.
For example:
Referring Link >> 302 to new page >> Correct page---------OK
Referring Link >> 302 to new page >> 302 to moved new page---------Lost PR
