Our Price Matching Policy

At Mediriser, we are dedicated to offering you the most competitive prices online. We maintain strong partnerships with our suppliers to establish minimum advertised pricing guidelines for all our competitors. This means that every other online store selling the same product is expected to offer it at the same price.

Price Match Guarantee

If, within 14 days of your purchase, you discover another online store offering a lower price for the same product, please bring it to our attention. We will promptly contact the brand to ensure they comply with the minimum advertised price policy. If you qualify for a refund, we will credit the price difference back to your credit card.

Your Confidence Matters

We want you to shop with absolute confidence, knowing that you are receiving the best possible price for the product. If you find that our own website has reduced the price of the item you ordered within 14 days of your purchase, we will also refund the price difference.

Requesting Your Partial Refund

To request a partial refund, simply follow these steps:

Email us at support@mediriser.com with links to the product on both our website and the other dealer's website where you found the price difference.

Ensure that you make this request within 14 days from the date of your order.

We will process the credit accordingly and ensure that you receive the best deal possible.

Limitations of Our Price Match Guarantee

While we are committed to providing competitive pricing, our Price Match Guarantee does come with certain limitations:

You must purchase the item from our website before requesting the Price Match Guarantee.

Promotions such as rebates, holiday sales, and "buy one, get one free" offers do not qualify.

The item must be in stock on the competitor's website and be sold as brand new.

The competitor must be an online store and may not have a physical retail location.

The website in question cannot be a discounter or auction site (e.g., eBay, Overstock, Walmart, Amazon, etc.).
