Riddle me this Batman...

How in the world can the Duckling's size 6 infant shoes cost THE SAME that my size 7 1/2 adult women's shoes do? The shoes use like 1/4 of the amount of materials...leather, cork, buckles, etc. that mine do.

Shouldn't they cost 1/4 the price?

P.S. Just got a call for the Blackwells...Kate has apparently left her little boy's shirt at Talbots. Just in case you know her, please pass that tidbit of info on, thanks.
