hello
i personally wouldn't buy frozen mince, from experience the amount of water that's in it makes it cook away to nothing and is rather tasteless. do asda do the 3 for £10 for mince like I think tesclos do? it might be worth in that respect shopping for some things for the month (if incomings allow) if not I like lidles mince. also have you tried bulking mince recipes out with red lentils or tinned beans? you just need to use a slightly stronger stock (in a bol or shep pie eg), but there are lots of different types of tinned beans on one offer or another.
I would only advise using dried beans if you had a pressure cooker or you're prepared to cook them in a mega-batch and then freeze them in old marg tubs of something. this is cos the cost of cooking them can make them more expensive than tinned.
herbs and spices btw are often lots cheaper in the worldfood aisle, just decant them in old screw top jars and keep in a dark place. tho only buy the mega-sized bags if you're going to use them often cos they can go a bit stale, I still use them like that tho, I just use a bit more. the little pots in herb section are stupidly expensive I find. some spices and tomato puree can make the blandest bean stew delicious.
re chicken... do you have a sharp knife and/or poultry shears? a chicken is fairly simple to joint yourself, it just takes a bit of practise (there are lots of online tutorials for it). a lot of the time buying a whole chicken is cheaper than joints, esp boobs which are usually a premium price. I freeze and save the offcuts for making stock (either in pressure cooker or slow cooker) with saved frozen veg peelings, offcuts etc, but again I know this isn't for everyone.
buying everyone at work lunch????? are you the manager? if not... don't! if you are, arrange the meeting at work and use office supplies. take enough for your coffee with you and 'forget' your purse

if they think you're tight then that's tough on them, they shouldn't be seeing you as a soft touch to get lunch. cheeky s**s

I know all about dental costs, was told I have beginnings of gum disease a few months ago and treatment and new dental supplies cost a fortune. luckily I found the toothpaste etc dentists recommended on the wilco site all on special offer so managed to stock up a bit. am back there in a couple of weeks (probably for more treatment) and I need a new night guard so I know the bill is going to be over £200!
I think a good cry at times is good to get the stress out of your system, but please try not to get overwhelmed. there are lots of lovely people here for you, whether it's to offer advice and tips or even that'll give moral support and send hugs when you need them.
one final thought, I used to do my budget by the week as was weekly paid and on a rubbish 7 hour contract and always found things a bit tight, but on weeks I had a few extra pounds I either stocked up on non-perishables or, as I ended up doing, saving it up so I could start shopping monthly.
I find if I shop monthly I can take advantage on offers. eg weekly budget one tin of something for 50p but buying for the month i'd get said tin on and offer at say £1.60 for 4 thereby saving money.
whatever you decide it has to work for you and your family, be manageable and not stress you too much. you've made a fab start and it can only get easier once you start getting used to it. try to think of it as a challenge rather than a drudge chore.
lots of big hugs
cor! that was a long message, but had to get it out of my head while I thought of it all, I only have a tiny peanut brain.
