Check around when you are want to buy new furniture. You can find massive price differences between shops to the exact parts. To make sure you are having the best option to your money, shop at a couple different outlets to find the absolute best value on that Clawfoot Tub or other special item.
Try multiple stores. Instead of going into a store and finding whatever is there, invest in going to more than one shop before you decide. This will enable you to get what you want and can give you a few options so you have significantly more to choose from.
