It won't really affect our family much at all. We very rarely eat out now, because even without PST its still freaking expensive for 6 people. I may think twice about popping by Timmies at first, but after awhile it just becomes normal.
Clothes for the kids will be a bit pricier, but I try to keep an eye on the flyers for good sales anyways, cuz it really pains my little dutch heart to pay full price for anything.
Apparently there will be HST on certain school supplies, but we use very little of that since we started homeschooling all four kids 3 years ago.
Pop is a once a week treat for my kids, so no worries there really. Chips we do eat more often, so I may buy a couple bags less a week, but that's minor.
If I didn't have kids I would def get rid of the home phone. They are old enough to be home on their own during the day, but I would not be comfortable leaving them home alone without a phone.
And I cut everyone's hair around here, even trim my own sometimes, or get one of the girls to do it for me.
So no, no plans to cut back really, since we don't spend a lot of money on 'extras'
