I got a photobook done from snapfish, and at a later stage some acrylic prints (printed directly onto the block, not paper then mounted).
The acrylics were a month delayed, (however, unlike the bonded or sandwich types you can get, the images were without error)
The photobook was nice, and done very quickly. However, there was an option to have a copy of each photo on the pages done as photos. These came out too dark compared to the photobook.
Somewhere the colour management obviously wasn't working properly.
If you search around, you will probably find some offers for 30-50 free 5x7 prints from snapfish, they give away a lot as starting deals (among other types of offers/half-prices).
