A great way of keeping the cost down is to ensure you order the correct amount of tiles for the area. Not ordering enough tiles will result in having to order more and pay additional delivery charges (note, there can also be shade differences between batches so its always best to order them altogether). Ordering too many can result in overspending and return fees.
To calculate how many tiles you need, you need to measure the area you wish to tile and add 10% extra for wastage.
