This looks to be different from the nescafe offer. You have to pay postage. Not sure what that is, but the Nescafe one was $5.95, according to the OP of that offer.
Same as the previous snapfish/payapal offer
* Offer is for one free 10.2x15.2 cms Photo Block
but
* Postage/Handling fees apply ($5.95 according to snapfish website)
