Hamilton residents will receive some budgeting pearls of wisdom as part of an upcoming series of author talks at Hamilton City Libraries.

Waikato author Jackie Gower, co-author of 'The $21 Challenge: We show you how to feed your family for a week on just $21', will be holding three talks at Hamilton City Libraries throughout February - at Glenview Library on Monday, 8 February at 10.30am; Dinsdale Library on Wednesday, 17 February at 11.15am; and Hillcrest Library on Wednesday, 24 February at 11.15am.

Written by Mrs Gower and Simple Savings website founder Fiona Lippey, The $21 Challenge is described as 'a very useful book for those on a budget'. During the author talks Mrs Gower will discuss the book and give some tips and ideas for families on a budget. Spot prizes and information handouts will also be available.

"Busy mums call the book their 'bible' and refer to it constantly for ways to use up bits and pieces in the kitchen, or make a little bit of 'nothing' into a delicious new meal," she said.

"What really makes us happy however are the people who have told us the book has given them a lifeline; particularly from families who are going through tough times. The realisation that they don't have to find $300 a week for groceries week in, week out is a huge relief for them. They have learned how to cook and shop smarter and are feeling much more positive
