Test it in the store. Nobody in north america expects they can buy something, walk away with it, and then have a right to return it simply because they don't "like it". A store may take it back but only because they are kind, not because they are under any legal obligation.
Remember there is always a flip side to returns. Either the seller eats a loss, or they put the now used object back on the shelf as new. That is why safety-related products have a zero-returns policy. Rock climbing gear is generally non-returnable. I probably would not buy climbing gear from any store that did returns for fear of getting used gear with unseen problems.
