When we decide to buy something, we normally set a budget which we do not like to surpass. However, when it comes to rugs, we should be a bit more flexible with the budget. After all we are purchasing an item that will last or even outlasts us. So going over the budget sensibly is expected. As it is commonly said; Buy cheaply, Pay dearly!
What it means is that in order to stick to budget sometimes we sacrifice the quality.
