Managing the cost of social commitments, e.g. Kids Birthdays, going to Weddings, entertaining Friends. Are these luxuries we can no longer afford?
I think you can still afford these things but you have to think smart about it. Usually a wedding has the following costs associated with it:
An outfit
A present
A day drinking
Travel
A night in the hotel
So from the above, dont buy new outfits, buy an actual present - as someone mentioned get something in a sale, or be creative and make something - when I got married a friend brought her camera, took lots of pics and made me a beautiful photo album as a present - it was a wonderful present. One of you drive to it, and that way only one person is drinking, and dont stay in the hotel, let the driver drive you both home - you really can go to a wedding cheaply if you do this.
As for kids parties - same applies, cheap thoughtful present, same clothes, if you are throwing the party yourself arrange it in such a way that you are not feeding a meal to hordes of children, just snacks.
Entertaining friends, dont do it with a meal, ask them round, tell them to bring their own booze, and provide cheap snacks (chips and dips, or LIDL frozen party snacks).
Whats the most cost effective way to Grocery shop? One bulk buy per month or week, or a few disciplined trips when needed?
We tend to do one large shop a month where we buy tinned goods, dried goods (like rice, sugar etc..) and then most weeks we buy fresh fruit/veg/staples (like milk/bread) in LIDL, and fresh meat (I buy in a butchers and avail of his deals). Generally there is a weekend a month where we dont shop at all and just live on the stuff in the freezer and whatever bits of fruit and veg are left over.
For lunches I buy an oyster of ham in the butchers (it costs a fiver if I buy it with a chicken - a tenner for both) and cut it in half, freeze half and boil the other half and slice it and use it for sandwiches for the week. I also cut the chicken in half, freeze half, roast the other half and use it for same - there is 2 weeks worth of lunches in a chicken and a ham - for a tenner. You may also get a dinner out of them as well.
I write a list before going grocery shopping and stick to the list. I used to find myself binning jars of stuff that Id bought to try or binning meat that had been sitting in the freezer for months waiting for me to make some particular meal with it - now I just buy what we actually like to eat and thats it.
LIDL/ALDI are cheap for the cleaning and personal hygiene products as well.
I also shop on ebay for bargains. Just last week I bought 2 pairs of summer sandals for 3 pound sterling each, the postage was 4 pounds - so net cost was less than a tenner per pair - and Ive already worn one pair to a wedding and been complimented on them.
