E-OMC seems to get a good rap on here, and I'm thinking of buying a couple of pairs of Keens from them. They're the only ones that have both my size and my wife's size

Anyone had any experience with their return/exchange process, so I know what I'm in for if things don't work out?
Or if the shoes develop a fault within warranty, can you deal with the local distributor?
They tell me their US$38 flat rate is insured USPS - will it be trackable?
Look forward to any tips.
Cheerio!
