Oh heavens I wish I'd knows about this site eons ago!
It has fantastic cards that you can personalize from bulk thank you cards to a sweet fathers day card with your kiddos picture on it.
Also, they frequently have codes available for free or discounted cards, so I've placed orders for 2 in the last two days and have paid a whopping $1.07 for both greeting cards to be sent to me. You can also have them sent straight to your recepient if you choose.
Use the link below to go straight to their website and check it out. Also, if I refer enough peeps I get a $15 credit; wha-bam!
