I have a question...I completed an offer and got credit but I'm questioning the amount credited to my account.

I'm looking for the Red Lobster $100 offer and can't find it. Any easy ways to search for an offer? .15 was put into my account and I thought it was for more. Same thing happened the other day when I was credited .02 for an offer (not a paid click) and I couldn't find the offer. Maybe I'm confused about how things credit and this is a really stupid question.

Thanks for any help!
