The funny thing is I just got an email that my $325 gift card purchase gave me a free year of Target circle (I didn't even realize I had the offer on my account) and also qualified me for the $30 bonus. So it seems like it was an issue with your purchase. If you click the dropdown arrow by your name on your target account in the upper right corner and click on target circle, and then in the middle of the page it has 5 headings (Deals, Bonus, Partners, Voting, Activity). Click on Activity and it will give you a breakdown as to what did and didn't qualify towards the bonus. Below is what my activity looks like for the purchase I just made of a $200 gift card, a $100 gift card, and a $25 gift card.
