Hallo.
sometimes I need plastic raw materials for my projects. The problem is
that in Italy they're difficult to procure in small quantities (an
example: I'd rather not purchasing 20 sqft garolite for my router
mounting plate!).

So sometimes I found McMasterCarr a convenient way: the problem with
them is they are insanely in love with DHL, which (both for direct cost
and income taxes) makes it much less convenient.

So I wonder If you can suggest alternative online retailers dealing this
kind of stuff (and, may be, they will be more willing to ship by USPS or
even surface mail)... or, if I am going too far OT, readdress me to a
more proper NG.

Thank you,
Luciano
