Two weeks ago, Apple was giving folks the heads-up for the upcoming Father's Day. That's this month, on the 15th, by the way. While the Mac maker didn't say anything about discounts on any products back then, this week has seen the Cupertino-based company offering rebates on (what else?) custom photo books and cards.

If you've missed out on this offer on Mother's day, you can still make it up to 50% of your genes by getting Dad a photo book, or card, nicely crafted in iPhoto or Aperture. Apple is offering a 20% discount through June 15. Starting today, you can only order one for express shipping. The deadline is June 8.

"Create a beautiful photo book Dad will treasure. Graduate in style with custom announcements, invitations or even a photo book keepsake. Order any photo book or cards by June 15, 2008 and get it at a 20% savings," Apple says.

Want to create a book or card in iPhoto? You can view a book tutorial here and a card tutorial here.

If you want to create your book in Aperture (don't forget to use the springbooks coupon code at checkout for 20% savings) have a look at this making-books-in-Aperture tutorial provided by company.

If you're already set to go with a book or card, just click Buy, select Use a Coupon and enter the offer code (Books: springbooks, Cards: gradcards).

The e-coupons for Books and Cards are valid with iPhoto '04 and later, Apple says. The e-coupons for Books are valid with all versions of Aperture, but they have no cash value. The e-coupons may be applied only to iPhoto Books and Cards, and Aperture Books, and may not be employed for the purchase of standalone prints, or calendars, Apple's terms and conditions say. Sure enough, each e-coupon may be used multiple times during the offer period.

The e-coupon may also be applied to the subtotal of the transaction, but not to shipping charges or taxes, while the company reserves the right to deny any use of or disregard any e-coupon that it deems "false" or "fraudulent."

This Father's Day discount is viable in all 50 United States, the District of Columbia and Canada.
