Father's Day  is this Sunday, and even if you don't have $100 to throw down for an awesome gift (stay tuned for more pocket-friendly priced gifts this week!), you can at least give him a great card he'll remember. Check out these five cards that are perfectly geeky — and perfectly priced.
Scrabble Card ($2)
If your pop is a Scrabble nerd, then I don't need to spell out how much he'll adore this card .
Darth Vader ($4)
Your dad may have his faults, but it's true — things could have been way worse .
Instead of sending dad a plain ol' card, send him a photo of you together with Postagram . Using the iPhone app, you can send a postcard with a pop-out photo that dad can keep on his fridge, his cube, or in his (huge) wallet.
Dad's a Geek ($4.50)
If your dad always has his nose in the science and tech section of the NYT, and can't get enough of his favorite sci-fi moves, he'll dig this science geek  card.
QR Code ($3.77)
If dad is on top of the QR code trend, then this is the card for him . When scanned with your mobile's QR code reader, dad will get a message that reads "Happy Father's Day."
