Seeed studio is one of those outfits that 'loves' to deal with DHL.
Here I find DHL to love tacking on extra fees - - - mostly because they
can - - - - just to get packages delivered. Then there is their insistence
on my sending my financial information to their http (note - - -insecure)
website - - - - so it is sorta easy to see why I find outfits that
'force' the use of DHL
to be reprehensible.
