we’ve actually completely discontinued using retailers.
the reasons are fundamentally economic: retailers take usually 30% of the list price, which is essentially the same profit margin we make as the designer/manufacturer. this is a huge deal for a company who is one person full time (me) plus a few part time people.
retailers pass on the shipping and import duty costs to you, so i believe the only thing you really save is convenience of not having to deal with UPS and duty payments (i apologize for this). that said, we only charge $40 for intl shipping (which costs us substantially more).
i wish we could do better, but commerce thrives on middle-man businesses (credit card companies, shipping, etc) so this was the choice we made to keep things running.
