Feldheim is one of the leading frum publishers. Basically it's a treasure trove to get the essentials--the chumash, siddurim, books of tehillim, books on kashrut and shabbat. Plus a bunch of other wonderful books. Great gift items. They often do have inventory reduction sales, not on the essentials but on the extras. I like to stock up at this time for gifts. Nice little books to give for presents such as birthdays, hostess gifts and other gift giving occasions.
