For a longer period, it was rather uncertain that GCA would continue.
Transportproblems (no insurance possibilities) and the new VAT rules in EU (more administration) made it uncertain to continue.
Now, adminstration (specially for VAT!) is changed, so at least GCA can continue.
The xtra costs will force prices to change.
Pricelist will only indicate prices without VAT, TVA, MWSt, btw.,
and axes will be listed on proforma invoice on ordering.
Up until now, shipoments willl be done via Postnl, and ALL shipments above € 80,00 will be insured.
