Price Matching

Dolphin Music brings you the best music gear at the best price. We are committed to superior customer service and have extensive product knowledge. However, in today’s market we may not always be aware of all the price fluctuations of the products we sell. So, we offer competitive price matching.

Please fill in the following form to request a price match.

What prices we will match?

We will compare prices for new, direct from manufacturer items, excluding any add-ons, options, or other special features which may affect price.

The item must be new and must be the exact same make and model (ie, the same size, version, etc.).

Since our postage charges are lower than most of the shops, the comparison price must be a "delivered cost" to the consumer.

If we are unable to verify the previous condition, we will notify you that we require additional information to verify the Price Match request. Our goal is to make this policy simple and hassle-free. We are committed to responding to your requests quickly.

The price you have found must be the Internet Retailer's regular, advertised price for a current and available item. The price you found cannot be a closeout, discontinued, blemished, year-end, inventory reduction, or any other type of advertised sale price.

Price Matching requests may not be combined with any other promotional discounts, specials or other price incentives.

Prices and price sources you have found which do not meet the above criteria or in which incomplete or inaccurate information is provided to us, will not be approved for our Price Match.

Please select your country/region

Choose the region you are shopping from to view products in your currency.

We have temporarily suspended processing of EUR payments, all orders will be charged in GBP.
