As an example, interestingly enough my latest was 
aquired at Sam's Club.  Pretty close to the 
regular memory books w/ acid free pages found in 
most craft stores, except w/ 25 page (room for 50 
cel) & only $15.

Most of my other books, though, have all been 
from JoAnn Fabrics or Michaels whenever one of 
them has had a 40% or 50% off coupon floating 
around.
