Can someone help me with these basic questions? I have been pulling my hair out trying to figure out the answers!

1. When doing offers, such as Big Bucks, how much of the offer do I really need to finish? I always do the first page (with email, and always check the box to do the 3-5 minute survey), then I do the first survey, then about 20 follow with different prizes!!! This is where I start to loose it!! Do I have to continue throught all of them to get credit?

2. When shopping through the SR link, if I use a discount code, which I may have received through an email or catalog, will I still get credit through SR? Or can I only use the coupons and codes listed on this site?

Thanks in advance!
