We work very hard to ensure that we offer the absolute best prices online. We work with our suppliers to ensure that they set minimum advertised pricing guidelines for all our competitors. This means that everyone else selling the same product online is supposed to be selling it at the same price.
If you find another online store that offers a lower price than us within 6 months of your purchase date, please let us know and we will contact the brand to ensure they are not breaking the minimum advertised price policy. If you qualify for a refund, you will be refunded the difference in price to your credit card.
We want you to feel confident that you are getting the absolute best price for the product you are ordering. If you find that our own website has a lower price for the same item you have ordered within 6 months of your purchase date we will refund the difference as well, as long as your request doesn't fall within the below stipulations.
To request your partial refund, simply email us a link to the product on our website and our competitor's website, within 6 months from the date of your order and we will process the credit accordingly.
