a bookshop

Shopping for gifts? Try your religious organizations and see what goods they're offering. Here's a link to one, the Sinsinawa Dominican's bookshop .

Since Natty mentioned it...
I did not find mound cake, but looky, you can get very delicious looking bread from these same folks: http://www.sinsinawa.org/Bread_Gifts/Bread.cfm

(the double "sin" in their name does give rise to some jokes)
