For the next 2 days over at Eversave you can get a voucher for $50 worth of custom photo cards from Photocard Creations for $20. However, if you are a new customer, you will get a $5 credit for signing up, which would bring your total down to just $15!
These are upscale, beautiful photo cards & a deal like this would make them much more affordable. The holiday cards have a minimum order of 50, but the invitations & announcements appear to have a 25 card minimum order. You can purchase your voucher from Eversave here.
