There is another aspect to living cheaply - never buy things when you need them. Lets ignore the growing and making aspect - and look to the fact that most people have to buy. Don't buy coffee when you need coffe - or washing up liquid when you need that. Buy it when its cheap - and buy a lot. We buy coffee six months worth at a time. There are often offers, so we buy it when its "buy one get one free" - and we buy a couple of trays. That lasts six months. When we get low, we look for another offer. Dishwasher liquid - we bought 5 x 20 litre drums - probably two years worth - but it was less than a quarter of the price per litre of a single supermarket bottle. It does take some storage space (but most of us have cupboards under the stairs etc. - even a small spare bedroom) - but it does save a heck of a lot of cash. This is the UK version of "couponing" as practiced in the US - don't be tempted by offers to buy things you don't normally use - but really stock up when things that are not perishable are half price or better. If you can find the space, it saves a heck of a lot of money. Start small, re-invest the savings. Use catering firms, bulk suppliers etc. I buy all my herbs and spices from catering and wholesale outlets. I can get between 10 and 50 times as much spices than supermarket packets for the same price. Buy whole spices - not ground - and grind as needed - it stays fresher that way.
This is no different than any other investment - any stock trader will tell you to buy and sell shares when the conditions are right - not when you need the money. So shop when the conditions are right - not when you need the product. Shopping for consumables is one of the major expenses in a household - so use some savvy
Couldnt agree more Red, another thing ive noticed is how much can be saved by buying loose items instead of packaged.
example from todays tesco prices
Quaker oats so simple original 12 x 27g packets = £2.29 or 71p per 100g
Quaker porridge oats 1kg = £1.99 or 20p per 100g
The same goes for fruit and veg if shop bought. If someone has to wash it and wrap in plastic then it will normally be 50% more on your bill.
