Gevalia is really making the rounds (grounds? HAHAHA) with their free coffee samples! So if you happened to miss the first two offers, now's your chance. I will accept unlimited quantities of free coffee samples, so this is no problem for me. Note: Target's website is apparently being a little weird in some browsers, so if it gives you any guff about "not being able to proceed without a code," try a different browser. The consensus seems to be that Firefox and Chrome won't work, but IE will, and Safari worked for me.
If you've received Target's beauty sample bags in the past, there's a new offer going on right now — but it works a little differently. Throughout the month of March, promo codes will randomly print on shoppers' receipts; enter that code on the sample page and you'll be able to sign up for your sample bag. Target claims that the codes are completely random and not tied to purchasing a certain number of beauty products, but other bloggers have noted that paying via debit card seems to improve your chances. So if you shop at Target this month, read your receipt carefully!
