Low Price Guarantee

At Holbren we believe we have the best pricing and total cost on the internet but if you do find a price on an item we sell in new condition we will match it and still maintain our low to free shipping rates.

The competing reseller must be authorized by the manufacturer to sell their product, have it in stock, and the company name must be verified. Holbren will price match drop ship items if we have to drop ship as well and that would only be some models of Byrd heads. Authorized resellers do not include Ebay sellers or other online sales websites where the name may be different than the company name and unverifiable. 

Price match guarantees are for the cost of the item and any applicable shipping a competitor may charge and include any sales, promotions or free shipping specials from competitors.

Send us an email to sales@holbren.com and we'll work it out.

30 Day Satisfaction Guarantee

If you are not completely satisfied with your purchase, we offer a 30 day satisfaction guarantee and the item can be returned for a full refund less shipping charges paid by the customer. The customer is responsible for all return shipping charges and credit will be applied when the item is received.

The only exclusion to this offer is items sold under the Byrd brand name, under most circumstances we must pass along a 25% restocking fee that we are charged.

If you wish to return an item, please email us at sales@holbren.com with the details.
