My CM last year bought my children presents worth about £10 each. Her husband does get a discount from his work.
However, she has an extended family situation where her grown up daughter and 2 children also live with her.
I feel obliged at their birthdays to chip in a small something but now with the credit crunch I feel that suddenly buying b.day & christmas for my CM, her son , and then her g.children a bit much financially.
