It's just a guess, but I'd bet lots of site mark down all of those cutesy heart-covered items either today or tomorrow. Keep an eye out for steals on these adorable goods. If you're extra-organized, make a list of who will need a small gift next year and get stocked up.
Sweet Heart Small Mug, $3.95
Quantities are limited on this one (and the large one is already sold out) but it is pretty adorable. Cram it with chocolates and tie on a Valentine. Even at full price for $4, it's still a cheapie.
This might be a good time to tell you that the adults in my house are not super into Valentine's Day, but my daughter ADORES it. She would love this apron. If you have a little girl in your life, this would make an adorable gift for next year. (Also? Already on sale!)
Not EXACTLY Valentine's Day, but super classy and usable year-round. (This one is also already marked down, but not a lot.)
You'll probably be able to get a good deal on these in-store (and not spend on Target's RIDICULOUS shipping fees), but how fun would it be to get a table full of Valentine's Day serveware and host a party for the kiddos next year?
Target also has LOTS of other fun things on clearance already, but these glittery cereal bowls kind of have me smitten. Just think how much fun they'd be full of candy or necklaces or hair clips.
