Rocksolid Guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, undergarments and swimwear excluded).

Swimwear and undergarments are only returnable if unworn with original tags attached. But if something’s not up to snuff or damaged upon delivery, you can bring it back.

The guarantee lasts longer than 30 days, but not forever. We’ll be fair about. We’re all members here.

Price match guarantee

If you see a lower price for this exact item advertised online, in print or in a store, give us a call at 1 (888) 847-0770.

If it’s identical, brand-new, in stock, and sold and shipped by a Canadian-based retailer, we’ll match that price.
