Query: Great idea, poor construction

I got a Gustbuster Metro umbrella on a friend's recommendation after my old, cheap $10 umbrella from Walmart took a dive. I received it in great condition and, being from rainy Seattle, was looking forward to getting good use out of this umbrella. After two days of use in almost zero wind ("gusts"), one of the elastic straps holding down the top portion of the umbella became unravelled. I emailed Gustbuster to see if this was covered under their lifetime satisfaction guarantee. They said it was, but I would have to pay to ship it to them, and give them $11 for return shipping. For a $35 umbrella? Uh, thanks but no thanks, I'll just save my $20 bucks and buy another Walmart umbrella like the one that lasted me 5 years! Disappointed.
