There is a really nice sale on barn door hardware today. Building your own door is so much less expensive and you can customize the door to make your space really cool.
If you do want to DIY your door, the hardware is the budget buster so this is something to take a look at when it is on sale.
This is just a simple, 8 foot sliding hardware set that normally retails for $129 and is on sale for $74.
Please note the sale is today only (as of 10am PST, 4/26/18) and may end at any time.
