My favourite sort of thread: 'cos I'm as tight as a gnat's chuff, me!
I buy almost everything from charity shops and car boot sales; clothes, kitchen stuff, furniture, the lot. My new dining room curtains are Laura Ashley, really thick and very good quality - lined AND insulated. They cost me £4 (and about half an hours worth of alterations on the sewing machine.) Seriously, find a local car boot - you would not believe what people are almost giving away. My bread machine is a Kenwood, had never really been used and it cost me £4..!
Our living room suite cost £75 from a charity shop - it was immaculate and people often ask us where we got it. XD
The living room also has M&S chenille throws over the sofas (£1, car boot) and Laura Ashley prints on the walls (£2 each, naice frames included!) There are wooden hand-turned lamps that cost me a quid each in a PDSA charity shop (OK I had to rewire them but the lamp holders and wires / plugs cost less than £3 from Wilkos.)
All my furniture is from junk shops, more or less: it's all art deco or art nouveau stuff which I've stripped of old dark varnish, it's much better quality than chipboard crap and will always look good.
My double bed is a white wrought iron one I got off ebay for £60...delivered!
I made wool duvets for us out of old blankets from charity shops after reading about them being better for allergy sufferers (I have rhinitis.) They cost £75 each if you buy them in a shop - or about a fiver each if you buy old wool blankets from charity shops and sew a cotton cover to them.
But my major money saving tip is: be practical. I can wallpaper and paint, strip wood, tile floors and walls, do carpentry and minor plumbing stuff, put up curtain rails and blinds, rewire and add in new plugs and lights and do about a million other DIY jobs. The money this saves you is phenomenal.
I recently converted our cellar into a storeroom myself - it was very dry and was just wasted space before, as there was just a dirty brick floor and crumbling paint everywhere which made storing things in it impractical. So I dry lined the walls, damp-proofed the floor, added better lighting, laid a new concrete floor, laid new lino and painted: total cost of materials about £500, result, one large, usable storage room.
Yes, all on me own!
Then I did the same in the outhouse: lined the walls, added a shelf made of an offcut of worktop and stuck the washer and dryer in there.
Also, get a sewing machine and learn to alter stuff. I can do clothes as well as basic stuff like curtains, and it means you can always adapt your bargains to fit.
Now...don't get me started on batch cooking...!
