can i still get a prize from an offer if i get all the referrals i needed but i did't
complete the offer myself.
No, but there are a few sites that might let you exchange a ref for your offer.. I've done it once but the site no longer exists.
Hotgifts4you may exchange a referral for your offer requirement.
I am working on Hotgifts4you if you are interested. PM me
Officially4free network allows you to get more referrals instead of completing offers or complete more offers instead of getting referrals on any site )
primodinero, 2dollardeal, customorderthis, zeropricetags all let you exchange an extra ref for doing an offer
