Buying custom blinds online moves one job from an installer to you: Measuring. The shade is then built to those numbers, which is why many retailers will not take custom products back at all. That makes the guarantee the real price of a mistake. Two retailers can charge the same for a roller shade and leave you in very different positions if it arrives half an inch short, or if the color looks wrong in your living room. Before comparing prices, compare what happens when something goes wrong.
A custom window treatment cannot be resold, so retailers protect themselves in the fine print. Across the industry, policies vary in ways that change the real cost of an order.
A low price with no protection can cost more than a slightly higher price with a strong guarantee if even a single window goes wrong.

Most shoppers look for one guarantee. In practice, there are five, and each covers a different problem.
| Protection | What it covers | Blindster's version |
| Fit guarantee | The product does not fit, including your own measuring error | Fit-or-Free® Guarantee, 60 days from delivery |
| Satisfaction guarantee | It fits, but you do not like it | 60-Day Satisfaction Guarantee, exchange or refund |
| Warranty | A manufacturing defect | Blindster Limited Warranty, 1 year |
| Price match | A lower advertised price elsewhere | Matched and beaten by 5% |
| Price adjustment | The retailer lowers its own price after you order | 30-Day Price Adjustment Guarantee |
Blindster's full terms are on its policies page. An optional Accident Protection Plan adds five years of coverage for accidental damage such as rips, stains, and pet damage.
A fit guarantee is the one that matters most for online buyers, because measuring is the step most likely to go wrong. Blindster's Fit-or-Free Guarantee covers a product that does not fit for any reason, including a measuring mistake.

A satisfaction guarantee covers the product that fits but disappoints, such as a color that reads differently in your light. Blindster's 60-Day Satisfaction Guarantee works in two steps.
For anyone searching for roller or roman shades with a 60-day satisfaction guarantee, the cover applies to Blindster-brand lines such as its roller shades and Premium roman shades.
Price protection guards the money side of the order, and the two policies work differently.
Every guarantee has exclusions, and they are worth reading before you order rather than after.

Use the same checklist on any retailer.
The best place to buy custom blinds is the one whose guarantees cover the mistakes you are most likely to make. For most online buyers, that means a fit guarantee that includes measuring errors, a satisfaction guarantee with a real refund option, and clocks that start at delivery. Read Blindster's guarantees and policies side by side with any retailer you are considering, and compare them line by line.
Can you return custom blinds?
It depends on the retailer. Many accept no returns on custom products. Blindster's 60-Day Satisfaction Guarantee offers an exchange first and a refund if nothing works, with a $500 cap per 12 months.
What happens if I measure my blinds wrong?
At Blindster, the Fit-or-Free Guarantee remakes the product for a $20 shipping charge per product, plus any price difference, if you report it within 60 days of delivery.
Does Blindster price match?
Yes. It matches a lower advertised price on the same or a comparable product within 5 business days of purchase and beats it by 5%.
What is a price adjustment guarantee?
If Blindster lowers the price of the exact product you bought within 30 days of your order, it refunds the difference once.
Are LEVOLOR products covered by Blindster's guarantees?
No. LEVOLOR products are excluded from Fit-or-Free, the satisfaction guarantee, and price match. They carry LEVOLOR's limited lifetime warranty instead.
How long is Blindster's warranty?
The Blindster Limited Warranty covers manufacturing defects for one year from receipt, including motors and remotes. It does not cover accidents, wear, or sun fading.
