Never pay full price.
Moving into a new home can be expensive, especially if you have recently purchased you own, or are moving out for the first time. Essentially, you are purchasing absolutely everything you need for an entire house so it's understandable that things might start adding up! Not paying full retail price is a great way to start managing costs, and there are some great options available to help you do this.
There are two options here, the first is a sale, there seems to be one every 3-6 months, so patience can pay off in dividends here, or, secondhand. Check out Gumtree, Facebook ads and local classifieds for good quality pieces in hard wearing, easy to clean materials. I wouldn't recommend buying a secondhand mattress or sofa. Stick to solid pieces that can cope well with a bit of detergent and water!
