The first step is to make sure you have a proper measurement of the place and location that you want to use the rug. The majority of handmade Persian rugs are unique pieces, so you cannot resize the rugs to match with your space. After you figure out what will be the right size, you can start looking affordable traditional area rugs or persian rugs online.
One of the major issues to buy an authentic rug online is that you can't touch it; you cannot feel the quality of the wool, thickness of the pile, and look at the real color. The color of a rug online is depended on a video card and monitor of your computer. However, if the online store offers a good return policy, those issues will not be any problem due to the fact you can save lots of money online vs. buying the same rugs from local rug dealers.
If you do not like the rug, usually up to 30 days you can send the rug back to the online dealer for a full refund. Check the seller's reputation, check their reviews, look for a company name in the search engine reviews. Make sure they offer a good return policy and compare their price with other online resellers.
Make sure the online dealers provide a certificate of authenticity for your rugs. This document will be important for insurance to propose and reselling the rugs in the future. All the rugs from reputable dealers have a certificate of authenticity and they assure you about the quality and craftsmanship of their rugs.
