Price Match Plus

We are committed to offering the best in performance outdoor gear, clothing and footwear at competitive prices. The brands and styles we carry offer excellent craftsmanship and fair pricing, and we check our prices frequently to ensure that you are receiving outstanding value on your purchases. If you find a lower price, you're covered under our Price Match Plus Guarantee: If you find an identical product (ie, the same size, color, season, etc.) offered by another US authorized online retailer, we will beat their price by 5% of the difference.

An Example: You find a backpack that we sell for $100 on a competitor's site for $90. That's a difference of $10. We'll gladly sell you the pack for $89.50:

Our Original Price	Their Price	Difference	5% of Difference	Match Plus Price
$100	$90	$10	$0.50	$89.50

Simply contact us before (or up to 14 days after) your purchase by email: customerservice@altrec.com or phone: 1-800-369-3949.
